Aldreth

Aldreth is a hamlet in Cambridgeshire with about 260 residents (2001 census). It is located near the larger village of Haddenham (where the population is listed) and falls under the same Parish council. Aldreth is surrounded by fenland on all sides and is close to the River Great Ouse.

Toponymy
The name "Aldreth" occurs as Alreheða in the 1170 Pipe rolls, and means "landing-place by the alders", from a combination of the Old English words for "alder" and "hythe". The name also occurs a number of times in the text of the 12th century Liber Eliensis, as Alreheðe, with one variant as Alhereðe.

Battles
Aldreth may have been the site of two battles  between Hereward the Wake (Anglo-Saxons) and William the Conqueror (Normans). Aldreth was one of three routes, or causeways, into the Isle of Ely at that time; Stuntney Causeway 2.25 mi to the south-east, the Earith Causeway 10 mi to the west-south-west and the Aldreth Causeway 7 mi south-west of the Isle of Ely.

Geology
The village is on an east–west running boulder clay (middle-Pleistocene till) ridge sitting on a belt of mainly Jurassic Kimmerigian clays running south-west from The Wash. To the east is a north–south running belt of geologically more recent Upper-Cretaceous Lower Greensand capped by Lower-Cretaceous Gault Clay; the whole area is surrounded by even more recent fen deposits. To the west, again running north-east—south-west, is a scarp belt of middle-Jurassic sedimentary rocks including limestone and sandstone.

The flat fenland countryside around the village, typical for this part of the region, lies about 16 ft above sea-level. The highest point in the village is 23 ft above sea-level and the highest point in the area is 85 ft at Ely, seven-mile (7 mi) north-east. In contrast, the highest point in Cambridgeshire, 479 ft above sea-level, is at Great Chishill, 21 mi almost due south. Holme at nine feet (9.02 ft) below sea-level is East Cambridgeshire's (and the United Kingdom's) lowest point, and is 18 mi north-west.

Community
Aldreth shares an annual village open day, Blossoms & Bygones, with neighbouring village Haddenham. The event, which includes tractor rides, vintage car and tractor displays, and open gardens, held its 40th anniversary in 2011 with a VE Day theme, with villagers dressed in 1940s costume.
