Summary of geological interest

At Armigers, south-west of Thaxted, a giant boulder sits on the grass not far from the roadside. It is approximately 2.5 x 1.5 metres in size and 1.2 meters tall. It consists of a yellow Jurassic sandstone containing numerous fossils such as bivalves and ammonites, and it probably originates in Lincolnshire.

The boulder is very weathered and has been here for some considerable time. It is claimed that it was found in the gravel pit north of Armigers, and if so, it would make it one of the largest glacial erratics in south-east England. Further research and investigation is required to establish its origin and history.
