Essex erratic boulders: a gazetteer The Gazetteer All measurements are in centimetres unless otherwise stated BASILDON DISTRICT No large erratics are known from this district. BRAINTREE DISTRICT Alphamstone In the vicinity of St. Barnabas Church (TL 878354) there are at least eleven sarsens; eight in the churchyard, two by the road and one inside the church (at the base of the west wall of the nave) (Rudge 1964). The largest stone (150x120x45) is in the churchyard adjacent to the west wall of the church. It is likely that there are others in the churchyard that are now completely buried. The abundance of sarsens here suggests that a former Pagan stone circle or monument may have existed on this site, all the stones being transported here by humans. St. Barnabas Church is mostly fourteenth century with Norman origins. On the roadside, outside a cottage (TL 871357), south-west of Ansell's Farm, is a sarsen (130x110x40). Bardfield Saling On the grass outside the entrance to the churchyard of St.Peter and St.Paul Church (TL 686265) is a 1.2 metre diameter boulder of weathered sandy limestone covered in lichen and moss. Bocking The old retaining wall surrounding the churchyard of St.Mary's Church (TL 757257) contains numerous small erratics including two of basalt (maximum 45 centimetres long). Bulmer Tye Several sarsens are situated by the private entrance road to Bulmer Brickworks (TL 832380). Castle Hedingham Next to and opposite the youth hostel (TL 786356) in Luces Lanc are two sarsens (the largest 90x50x50). Finchingfield A large and splendid boulder of basalt (85x70x50) lies by the roadside (TL 685329) on the left hand side a few metres from the village green on the road north out of the village.
