Talk:List of highest points in London

Suggested additional entries/deletions
Might I propose The Ridge, Orpington - according to the contour mapping on openstreetmap.org, many of the properties in this street are around 110m above sea level. — Preceding unsigned comment added by 81.96.3.228 (talk) 14:33, 1 January 2013 (UTC)
 * The OS Explorer also has a closed 110m contour around the Ridge. Pterre (talk) 21:21, 1 January 2013 (UTC)

Are artificial hills allowed? There is a 135m contour around the edge of the grassed-over covered reservoir on which Hampstead Observatory sits, Lower Terrace NW3. Also Belmont, Harrow is 105m - OS trig point. Jimroland (talk) 01:00, 28 February 2013 (UTC) Also spot height of 104m on covered reservoir beside Woodcock Hill, Harefield 103m. Any problem with all these featuring in italic with explanatory footnote, in addition to both respective natural heights? Jimroland (talk) 00:21, 1 March 2013 (UTC)

Also any reason to keep Highgate Hill 100m point which is not a hilltop, merely the meeting point of three boroughs? Jimroland (talk) 01:00, 28 February 2013 (UTC) Also no sign on map of a summit at Harrow Weald Common 145m nor at Bournwell Hill 115m, anyone else have cartographic evidence of these? There are at least 20 more pronounced high points not yet added to the list. Jimroland (talk) 00:21, 1 March 2013 (UTC)

Other points
Is this a work in progress or definitive list? I would add Muswell Hill. No spot-height above 100m on Explorer maps, but Explorer 173 has a closed 100m contour around the top and Fortis Green, and unlabelled but presumably 105m contour just behind the library,. I'll dig out my old 6" paper map and see if it has some better-placed spot heights in shillings.
 * Confirmed: The old OS 1:10,560 sheet TQ28NE dated 1968 has spot heights at all the main road junctions. These include 331 ft at the roundabout at the top of the hill, 335 ft at the top of St James's Lane and 340 ft at the top of Fortis Green . Hey is it just me or does ({convert}) make 340ft lower than 331 ft? Pterre (talk) 21:53, 2 February 2008 (UTC)
 * Please add to the list. I've deliberately not put in ranking numbers to allow extra points. MRSC • Talk 22:45, 2 February 2008 (UTC)

This source gives the following highest points for north London, but does not have grid references.


 * Oxhey Hill (438 ft.) <appears to be same as potter st hill, top of which is outside greater london in any case. <what is wrong with including highest known elevation of it in Greater London as you did with Deacons Hill, Edgware? The 134m on Landranger by Potter St Hill is positioned as if it refers to a point in Greater London? Jimroland (talk) 00:29, 1 March 2013 (UTC)
 * Harrow Weald Common (475 ft.) <added
 * Bushey Heath (504 ft.) <already in
 * Deacons Hill, Edgware (478 ft.) <highest point of this hill is outside greater london, but have added one inside. There are several hills of this name, though.
 * Highwood Hill (443 ft.) <done
 * Harrow Hill (408 ft.) <done
 * Hampstead 'Jack Straw's Castle' (440 ft.) <already in
 * Highgate Hill (410 ft.) <already in

Only one is a direct match for location and height. It would be good to match these up to a grid reference. MRSC • Talk 08:10, 3 February 2008 (UTC)

Within M25
If you include places within the M25 there is also the High Beach area which gets above 110m around and west of Ambresbury Banks is a spot height of 117m at  Pterre (talk) 20:37, 2 February 2008 (UTC)
 * It should only include places within Greater London. MRSC • Talk 22:36, 2 February 2008 (UTC)
 * Given that, see below "greater london" Never mind Colt .55 (talk) 13:32, 12 August 2011 (UTC)

Heights of hills per source
When checking the heights of the hills in the source quoted I noticed that they were given in metres first. Therefore it seems appropriate to follow this in the article. Putting them the other way round could lead to rounding errors, and if a hill has been resurveyed and found to be different, this might be missed if the list is feet first. Michael Glass (talk) 13:12, 2 August 2009 (UTC)

There are several other reasons why this article should put the metric measures first. I am willing to make the article metric first. Are there any comments, suggestions or objections? Michael Glass (talk) 11:39, 16 March 2010 (UTC)
 * Heights in metres are used in all the modern maps.
 * Similar articles, such as the lists of tallest buildings  or the tallest hills and mountains in Great Britain  are metric first.


 * When making the changes I noticed that some of the high points were not properly supported by the two sources cited (or where a cited source gave another value). I have placed citation notices where this occurred. Michael Glass (talk) 11:15, 19 March 2010 (UTC)

This is a bit odd without a prominence criteria. For instance, you scarcely have to descend at all to get between Sydenham Hill and Westow Hill. Tom k&amp;e (talk) 18:14, 28 June 2010 (UTC)

What about natural highest points in the City and Westminster?
These peaks I note are nearly all technically part of London since the creation of Greater London. What about the City and Westminster? In the City there is a plaque at Panyer Alley which bears rhyme: 'When ye have sought the cittye round/yet still is this the highest ground' but a Ward Lock 1928 guide to London says 'that honour belongs more to Cornhill'. Some discussion would make good comparison.Cloptonson (talk) 11:25, 14 August 2020 (UTC)

Harrow vs Stanmore Hill
An unnamed hill in Harrow-on-Hill is claimed to be the only isolated peak with the rest being parts of ridges. A recent (now reverted) edit suggested this honour belongs to the higher Stanmore Hill. The hill next to Church Hill, Harrow is indeed isolated. Stanmore Hill, however, is on a ridge that includes Harrow Weald Common, Pinner Hill and Woodcock Hill. Apologies for doing original research using OS maps.

By the way, St Mary's church is built on the summit of the unnamed hill. Should we use that as the hill's name? OrewaTel (talk) 21:40, 6 January 2022 (UTC)
