Dedham has a central nuclear settlement around the Church and the junction of Mill Lane and the High Street (part of the B1029).In 1582–1587, a schismatic Presbyterian Christian group called the Dedham Classis, which included dozens of members opposed to the established church, was active in north-east Essex.In 1937, Cedric Morris and Arthur Lett-Haines founded the East Anglian School of Painting and Drawing at Dedham.[6] Keating's best known painting, a Constable pastiche called The Haywain in Reverse, is reportedly on display in the Granary Barn and Museum in Flatford.[11] Agriculture is also important with mainly arable land (sugar beet and wheat) but also cattle grazing on the water meadows and some sheep on Grove Hill.
