The church can only be approached by a pedestrian footpath.[8] The redbrick chancel was built between 1199 and 1221, with the nave being added in the 14th century and built of sarsen stone.[1][9] On the south wall is a scratch dial.[10] The interior has a font from the 13th century and a rood screen from the 15th.[9] The pulpit, altar rail and pews are from the 19th century.[1] There is a trefoiledpiscina, a shallow basin used for washing the communion vessels.[1] Monuments include wall tablets to Henry Webb (died 1776), John Nalder (1794), and Elizabeth Nalder (1835).[1]
In the 1660s the church was visited by John Aubrey, who described the memorials and tombs he saw.[11] In 1857 the church underwent a major restoration by Thomas Henry Wyatt.[1] This included replacement of the original wooden tower with the current stone structure which contains three bells dating from the 17th century.[9] At this point the walls were rendered and whitewashed.[1]
Parish
The benefice was united with that of Winterbourne Monkton in 1865.[12] In 1929 the union was severed, and Berwick was instead united with Winterbourne Bassett.[13] In 1952 the union was again dissolved, in order that the incumbent of the united benefice of Avebury with Winterbourne Monkton could also hold Berwick.[14] Those benefices were united in 1970, and their three parishes united at the same time;[15] in 1975 a team ministry was created for the area,[16] which became known as the Upper Kennet benefice.[7]
