Limehouse Basin



Limehouse Basin is a body of water 2 miles east of London Bridge that is also a navigable link between the River Thames and two of London's canals. First dug in 1820 as the eastern terminus of the new Regent's Canal, its wet area was less than 5 acre originally, but it was gradually enlarged in the Victorian era, reaching a maximum of double that size, when it was given its characteristic oblique entrance lock, big enough to admit 2,000-ton ships.

Throughout its working life the basin was better known as the Regent's Canal Dock, and was used to transship goods between the old Port of London and the English canal system. Cargoes handled were chiefly coal and timber, but also ice, and even circus animals, Russian oil and First World War submarines. Sailing ships delivered cargoes there until the Second World War, and can be seen in surviving films and paintings. The dock closed for transshipment in 1969 and eventually passed into disuse. Following closure of the basin and much of the wider London docks, the surroundings were redeveloped for housing and leisure in the late 20th century. Sometimes now referred to as the Limehouse Marina, the Basin lies between the Docklands Light Railway (DLR) line and historic Narrow Street; the Limehouse Link tunnel passes beneath. Directly to the east is Ropemaker's Fields, a small park.

Fuel for London; Thames congestion
To warm their homes and cook their food Londoners at one time burned wood, but local woodlands, though managed as renewable resources, could not keep up with the rising demand. Thus by the 18th century the town's fuel was chiefly coal, imported from Newcastle upon Tyne by sea — hence, sea coal. It was transported in colliers, typically small brigs. Because voyages could be extremely hazardous, these were built for strength, "certainly not for looks".

Arriving in the Thames, a collier tried to find a mooring in the highly congested Pool of London. Once moored, a fleet of small barges, called lighters, relieved her of her cargo. But these lighters were used as floating warehouses, perhaps taking a long time to unload. They attracted "River-Pirates, Night-Plunderers, Lightermen, Burgemen, Watermen, Bumboatmen, and Peter-Boatmen", to the point that rivermen rarely paid for their coals, or so said Patrick Colquhoun, founder of the Thames River Police.

Linking Port to English canal system
Some inland towns depended on the English canal system for their coals, yet access from the Pool of London was difficult, the nearest Thames link being at Brentford. The Regent's Canal Company proposed to tackle this problem by digging their canal to skirt round existing London to the north. Horse-towed barges would convey goods from Limehouse to the Paddington Branch of the Grand Union Canal (opened 1801), and onwards. "The Regent's Canal was intended to and still does bring the Thames into watery contact with, say, Birmingham". Later, it was sometimes found cheaper to import coal in the opposite direction. The Newcastle mine owners were in a cartel to keep up prices and, when they went too far, midland coalfields sent their produce to London down the Regent's Canal.

Where a canal joined a tidal river there was usually a small basin where barges could wait for the right state of the tide to go over. The Regent's Canal Company, short of capital, thought it would be enough to provide a small 1 $1/2$ acre basin of that sort at Limehouse. However, they were converted to a bolder idea: making it big enough to receive the Newcastle sailing colliers themselves, which could then unload at their convenience.

The Basin: original 1820 version


The chief engineer was James Morgan and the contractor was Hugh McIntosh; the basin's wet area was 4 $1/2$ acres.

The basin formally opened on 1 August 1820. The Regent's Canal entered the basin through the Commercial Road Lock, which is still in use.

The original basin was rudimentary. It was not faced with stone or brick but, to save disposal of spoil, had earthen banks gradually sloping down to the bottom, which was 18 ft below Trinity High Water. Since ships could not get alongside to moor there were wooden jetties for discharging goods to local merchants, but they had been built too high. There were not enough mooring buoys.

The Basin was gradually enlarged in the 19th century by digging east and southeast (see below). At the century's end parts of the west and north banks were sloping still.

Thames entrance
The Basin was dug some distance inland, since the riverfront was built up. It was connected to the Thames by a short canal that was crossed by two streets. It had a pound lock, and could admit ships of about 10 metres beam. (This canal outlet ran more or less where Horseferry Road does today as it joins Narrow Street.) Traffic on Narrow Street crossed the canal by a swing bridge, which could pivot out to let vessels pass, driven by labourers who worked capstans (see artist's impression).

The canal outlet was made nearly square-on to the river, but it turned out to be a bad choice. When ships were trying to dock or undock, the local set of the tide flowed crossways, making it very difficult. In the first five months' service only 15 loaded ships entered the dock.

Not only ships, but already-laden barges entered the Basin from the Thames.

Not the first Limehouse basin
Limehouse Basin was the third structure of that name in London. In any case half of it lay in the parish of Ratcliff, not Limehouse. Hence throughout its working life it was better known as the Regent's Canal Dock; its "RCD" flag can be seen in the 1826 artist's impression.

Muscle power: coal-whipping
Coal was unloaded in the Basin from ships to barges. Until 1853 it was done entirely by human muscle power in a method called whipping. Four men down in the ship's hold put lumps of coal into a basket as fast as they could. Up on deck, another four men, when they guessed the basket should be full, ran up a crude ladder and jumped down onto the deck simultaneously, each throwing his weight onto a rope passing over a pulley: this jerked (or whipped) the basket out of the hold. Keeping up the momentum, a ninth man tipped the contents into a weighing machine which shot them into a barge. The whole thing was done in silence. A nine-man gang was expected to unload 49 tons of a coal a day; more often, according to Henry Mayhew, they achieved double that amount — during which each rope man climbed a total distance of nearly 1 $1/2$ vertical miles — and sometimes more.

Modifications and success
The proprietors soon fixed the teething troubles about the jetties and mooring buoys and the project became a success. By 1830, twenty to fifty vessels were entering or leaving the basin on each tide, typical large users being the London gasworks companies.

To cope with the currents a timber structure was erected to protect vessels being driven sideways (illustration). Nevertheless, wrote engineer John Baldry Redman in 1848, the entrance bore "a very bad character".

The London and Blackwall Railway arrived in 1840. Built on a viaduct, its arches skirted the northern edge of the dock, sometimes actually crossing the water. Thus the dock included a small basin on the other side of the railway line where barges could enter; it was not filled in until 1926. The railway continued to carry passengers until 1922 and goods until 1964, when it was abandoned, and was in danger of demolition, but its "fine" arches (by Robert Stephenson and George Bidder) were preserved as a listed building; today, they are used by the Docklands Light Railway.

The dock was enlarged several times (by 1848 the water area was 8 $1/2$ or 9 acres) and, in 1849, to cope with increasing congestion, a second outlet to the river was made for barge traffic.

In 1851 severe competition arrived: the railway companies penetrated the coal trade. Not only was coal from Yorkshire and the Midlands carried direct to King's Cross by the Great Northern Railway, but the North London Railway opened a line to the West India Docks, whose Poplar Dock could handle the latest large, efficient twin-screw steam colliers.

In Limehouse Basin, human muscle could not unload coal fast enough; electrical power was not yet practical; so in 1853 hydraulic power was fitted. Energy was stored in hydraulic accumulators (a heavy weight on a water column driven up a tower by a steam engine), a cutting edge technology at the time. It drove hydraulic cranes.

Mid-Victorian improvements (1870)
By 1865, the Basin was overcrowded. The old ship canal was not wide enough for the big steam colliers that were winning the business. It was the only dock entrance in London too narrow to admit the Fire Brigade's floating engine (a paddle-wheeler). A major scheme of improvements was carried out. The work was done by the Company's own employees under their chief engineer, Edwin Thomas.

The wet area was increased to 10 acres, the most it ever attained. A new river wall was erected. Meanwhile, it was business as usual, for the shipping traffic continued to come and go, floating in the old basin while protected by an earthen dam (see illustration).

Ship lock
The most important innovation was the new ship lock, which was 18.5 metre wide, and built slantwise to avoid the previous troubles. It was 8 $undefined 1/2$ metres deep over the sills. Major parts were made of Bramley Fall stone or Cornish granite. It could admit sea-going vessels of 2,000 tons net register, far more than would be possible now (today's lock is built inside the 1869 original). It was a two-compartment lock, and hence there were three lock gates, each formed by a pair of leaves. Each 80-ton gate leaf rested on a massive granite pivot stone. Most of those stones — with their telltale circular depressions — have been preserved, and today are laid out on display on the western side of the Basin.

Limehouse Basin now had three entrances from the Thames. The old ship lock was closed off by 1880, but the barge lock continued to exist until about 1924.

The accumulator tower


To work the heavy lock gates, hydraulic power was used; it also worked the swing bridge over Narrow Street, and continued to power the hydraulic cranes. For this purpose a new hydraulic accumulator was built with an unusual octagonal brick tower.

In 1973, investigators found the remains of the tower and at first mistook it for a railway signalling installation. It is now recognised as one of the oldest surviving accumulator towers in the world and is a Grade II listed building, being open every year during Open House Weekend.

Jobs
Alan H. Faulkner wrote that in 1907 Limehouse Basin employed (amongst others) a dock master, six policemen, thirteen crane drivers, and a diver and his mate.

Exotic cargoes and transport
The Company made efforts to diversify the dock's trade beyond coal and timber and attracted miscellaneous shipping.

Edible ice
Before mechanical refrigeration was commonplace, Limehouse Basin was a centre for the importation of high grade ice, in demand by caterers, confectioners and hospitals. Ice, pure enough for human consumption, was cut in blocks from frozen Norwegian lakes, shipped to Limehouse Basin, and stored in ice wells located near the Regent's Canal. The first to do this was William Leftwich. His enormous Park Crescent West ice well near Regent's Park has been rediscovered recently under the streets of Marylebone. He built ice wells in Cumberland Market and Camden Market, also supplied by the Regent's Canal from Limehouse Basin, One, the deepest ever dug, survives to this day.

Ice cream was a luxury for the well-to-do until Carlo Gatti introduced it to Londoners as street food — his penny ices. He built two ice wells at Kings Cross; one of them can be visited at the London Canal Museum. Gatti's depot was on the north-east side of Limehouse Basin for many years. At least 15 ice ships a year were still arriving there in 1912.

Ice had six different medical uses at the East End's London Hospital wrote their Matron, Eva Luckes. At one time it was commended as a safer anaesthetic than chloroform for "minor" amputations e.g. finger removals.

Cruises to Liverpool
In the Victorian era there was a weekly passenger service from Limehouse Basin to Liverpool; the round trip could be booked as a holiday cruise. Leaving on Saturday mornings, ships steamed round the west coast calling at Plymouth and Falmouth arriving in the Mersey on Wednesdays. The fare was £1 plus meals. One who had tried it said it was not recommendable during the equinoctial gales. Another said there were cabins but a passenger might have to sleep in the lifeboat.

Oil tankers
Some of the earliest practical oil tankers — before those evolved, ships routinely transported oil in barrels — docked in the Limehouse Basin in 1886. One was the innovative oil-fired Russian steamer Sviet with petroleum from the Baku oilfields; another was the American Crusader a wooden sailing tanker. The ships were designed to pump out their cargo quickly, saving valuable docking time, but could not do so at Limehouse Basin, because there were no bulk storage facilities. It had to be piped overland to barges in Limehouse Cut.



Circus animals
The Limehouse Basin between the wars was used to import animals — including lions, tigers, elephants, polar bears and sea lions — on their way to the London and provincial circuses. Once, 14 tigers arrived in one batch.

Submarines
After the First World War 25 German submarines were towed into Limehouse Basin and broken up by scrap merchants George Cohen & Sons, whose business was located between Commercial Road lock and the station.

Oranges
Near present-day Medland House in the 1920s were electric cranes for handling fruit cargoes from Spain.

20th-century sailing ships
The use of sailing ships to deliver timber at Limehouse Basin continued up to WW2. Labour-intensive, it was financially viable because most crewmen were youths who were paid no wages. The ships can be seen in films of the silent era; a painting at the National Maritime Museum by Norman Janes shows three 3-masted sailing vessels there at the same time.

The Regent's Canal dock had its own customs house. The latest was built around 1905-10, and stood on the river side of the Thames lock. Today, it is a listed building, and is used as a Gordon Ramsay gastropub.

Relation with Limehouse Cut


Limehouse Cut to the east — an older canal that conveyed grain traffic from the River Lea and had its own basin and exit to the Thames — had no historic connection with the Regent's Canal. In 1854, however, there was talk of a takeover and a link was dug to Limehouse Basin. The takeover was opposed by bargemen on the rivers Lea and Stort who did not like being under Regent's Canal regulations. The proposal was defeated and in 1864 the link was filled in.

Apart from that brief interlude there was no connection between Limehouse Basin and the Cut for another hundred years, although some old maps may suggest otherwise.

In 1968 Limehouse Cut's old Thames exit was stopped up and, by cutting a 200 foot (60 metre) channel, it was made to discharge directly into Limehouse Basin. (The new link ran north of what is now Victory Place. The old link had run to the south of the site.)

Lifeboats
The Victorian era's lifeboats, sponsored by the Royal National Lifeboat Institution, were built nearby on the Limehouse Cut at Forrestt's boatyard, but for publicity were often given their harbour trials in Limehouse Basin. They were tipped upside down and allowed to fill with water: if they self-righted, spontaneously ejecting the water, they passed. Reportedly these boats saved upwards of 12,000 lives.

In national politics
On 1 January 1948 the Regent's Canal was nationalised. On 27 May 1948 eleven dockers were ordered to load bags of a chemical onto a ship docked in Limehouse Basin. Because the chemical stained their skin and clothing they felt it was a dangerous cargo and refused to handle it, unless for extra payment of their own specifying. This was a direct challenge to the National Dock Labour Scheme instituted by the newly elected Labour government, which had replaced the old system of casual employment by a legal right to minimum work, holidays, sick pay and pensions, but under a regime where dockers had to obey orders or face disciplinary action (although they could appeal). The dispute escalated to a London-wide dock strike, spreading to Liverpool, whereupon the Attlee government invoked emergency powers and ordered troops to unload food vessels.

Swing bridge
The swing bridge that carries Narrow Street over the Thames lock is a 1961 replacement. Built on Teesside, to get it to London it was made into a seaworthy pontoon and towed down the North Sea.

Derelict
Burning coal in London was made illegal. The last commercial barge traffic in Limehouse Basin was in April 1968. It closed as a transshipment dock in 1969, though it continued to be visited by ships with scrap metal for Cohens as late as 1980. It became a bleak, derelict industrial zone. Planners wanted to fill it in "because they said children would fall in and drown". Also, the area was blighted by traffic congestion, access to the Isle of Dogs being poor. The Greater London Council proposed to demolish part of the railway viaduct and replace it by a 4-lane dual carriageway; an alternative route was between the Thames and the Basin, which would have cut through the exit lock.

Controversy
The redevelopment of the Basin for housing started in 1981 when the British Waterways Board organised an architectural competition. The winner was a £70 million scheme by the controversial architects Richard Seifert and Partners. It called for half of the Basin to be filled in to provide 100,000 square feet of offices and 400 luxury houses. It was strongly opposed by local residents, including David Owen, and was refused by the planning inspector who, however, was overruled by the Secretary of State. The architectural controversy attracted Prince Charles, who made a surprise visit to the Basin. The scheme was never fulfilled, except for Goodhart Place. Instead, the Basin was developed in phases, as and when the financial climate permitted.

Under the Basin: Limehouse Link
The answer to traffic congestion, said the London Docklands Development Corporation, was to run the Limehouse Link tunnel under the northern arc of the Basin. No precedent existed for such a large scale underground structure in those conditions. Since it was close to the DLR, precautions were needed to stop ground movements from collapsing the 150-year old brick viaduct.

The top ground was first consolidated by removing silt with a floating dredger and replacing it with North Sea aggregate to reclaim a stretch of dry land. The tunnel was made by the cut and cover, bottom up method. The trench was excavated inside a temporary cofferdam formed by massive piles braced by steel struts. The piles were very difficult to drive in the over-consolidated London Clay — and afterwards to remove. The first test pile was driven by Margaret Thatcher on 20 November 1989. Further precautions were taken to weight the base slab — if the groundwater pressure is high enough, even a concrete tunnel will float — and also not to form a new hydraulic connection between the Basin and the aquifer in the lowest stratum of the Woolwich and Reading Beds. The Regent's Canal was closed off for a year.

The four Marina Heights buildings were afterwards built over the tunnel. Wet basin area was restored in some other places e.g. the canal mouths by removing the marine aggregate.

New lock
The old mid-Victorian shiplock was large and used a lot of water, so in 1988-9 the Thames lock was rebuilt to much smaller dimensions. The new lock is only 24 feet (7.3 metres) wide — even less than the 1820 original — and the depth over the sills is 10 feet. It was rebuilt within the confines of the 1869 ship lock, whose outline can still be seen.

Amenities
Facilities alongside the Basin include a Gordon Ramsay gastropub, a tai chi academy, a gym, a kayak hire, a fine arts bronze foundry and gallery, and a cosmetic dental practice. Immediately near is the historic pub The Grapes, an Italian restaurant, a hair studio and a dry cleaner. In Ropemaker's Fields (a small park immediately to the east) there is a children's playground and a tennis court. Limehouse DLR station is beside the northwestern corner of the Basin. St Anne's Limehouse (1730), a Grade-1 listed building by Nicholas Hawksmoor, is a familiar landmark.

The canals offer recreation for narrowboats and kayaks; their towpaths, for walkers and cyclists. A six-mile round trip is: up the Limehouse Cut to join the Lee Navigation, then west by Duckett's Canal to join the Regent's Canal, then south back to Limehouse Basin.

Housing immediately alongside the Basin includes Goodhart Place, the apartment blocks Medland House, Berglen Court, Pinnacle 1 (awarded Best Apartment Building 2001), Marina Heights (four), Pinnacle 2, two terraced town houses and Victory Place. The Basin (excluding its buildings) is part of the Narrow Street Conservation Area. Canary Wharf is within walking distance; the scenic river route is across Narrow Street and using the bridge over Limekiln Dock. It can also be accessed by the 135 and D3 buses, or by the DLR.

Marina
The Cruising Association has a purpose-built headquarters at Limehouse Basin, where a number of vessels, both sea-going and narrowboat type, are permanently moored. There are facilities appropriate to a marina, such as secure jetties, diesel supply, laundry, shower, chemical toilet disposal, a pump-out and a chandlery.

"According to several boating associations", "the Limehouse Basin is a vital ‘port of refuge’ for departing and visiting craft from further down the tidal Thames and the Continent, due to providing the only lock in central London with an adequate tidal window for barges travelling downstream from the non-tidal Thames and other moorings and basins."

Of the berths, 75 are for permanent waterside living; others are for leisure use, wintering vessels, or visitors. The Thames lock operates 2 hours either side of low water.

At the Marina Office a plaque commemorates Stephen Maynard, a fireman who lost his life on 25 January 1980 putting out a ship fire in the dock: he was 26. In 2016 colleagues were still holding an annual minute's silence in his memory.

How deep is Limehouse Basin?
The depth of the Basin is variable. When it used to be a working dock it was supposed to be at least 6 metres deep and regularly dredged to keep to that standard; but this is no longer so. The Limehouse Link tunnel was made deep enough to give a minimum draft of 3 metres for canal barges. At the Thames entrance lock the depth over the sills is also 3 metres.

Wildlife
According to the Canal & River Trust "Limehouse Basin sits at the junction of three important 'green corridors'. The River Thames, Regent's Canal and Limehouse Cut all meet here, each providing a green highway along which wildlife can move around the built up area."

Birds that live there or are regular visitors include coots, moorhen, geese, black headed gulls, ducks (including red-crested pochards), cormorants, common tern, grey heron, and the occasional kingfisher. There is usually a pair of nesting mute swans.

Fish include bream, roach, pike and occasional eels.

In some hot seasons a "green carpet" descends from the canals and can cover much of the Basin. This is not "algae", but duckweed. While it can be a nuisance on canals, it is harmless to humans and is an important high-protein food source for waterfowl.

In literature and broadcasting


Maidens' Trip (1948) by Emma Smith describes the wartime experiences of three "dainty young girls" who, as part of their national service, volunteered to load and navigate barges from Limehouse Basin to Birmingham and back — with only a bucket for a lavatory. Recalled Smith:"1944 was the year the doodle-bugs were being sent over from the Continent, and the job of taking the boats down to the docks for loading and away again was like an adrenalin-fuelled dash in and out of Tom Tiddler's ground. Nobody wanted to get caught for the night in Limehouse Basin. It was said, and probably with truth, that if a bomb were to drop in the basin every boat lying there would be sucked under and sunk." (Although no V1 flying bombs did drop into Limehouse Basin, three exploded within yards of it.)

The real canal boatmen travelled with their families, their wives giving birth on board; the babies (wrote Smith) were "little creatures who would pass their early days chained for safety to the chimney-pots".

The book was adapted for radio (1968) and television (1977).

Archaeology
Archaeologists had an opportunity to look underground when Limehouse Basin was redeveloped. Beside the Thames lock, at Victoria Wharf, a team found the remains of an earlier dock, whose timbers they dated to 1584-5 by dendrochronology. There was evidence of shipbuilding around the time of the Spanish Armada. Coins and other finds came from as far afield as Cuba, Persia, and China.

While excavating the Basin for the Limehouse Link a 16th-century cannon was found.

Another team excavated a site on the other side of the lock. Finds showed the 16th and 17th century occupants were exceptionally wealthy men and women. "Meals were likely to be served on fine Mediterranean tableware and wine taken in glasses derived from the finest production centres of the age". The archaeologists realised it had been inhabited by retired pirates of the Caribbean, some of whom they were able to identify by name.
