An archaeological watching brief was undertaken by Colchester Archaeological Trust during the installation of an interpretation panel in Gosbecks Archaeological Park (planning application number 150573). <1> The post-hole for the interpretation panel was dug approximately 260mm square and 550mm deep. The upper 100mm was turf and modern topsoil. This sealed a greyish-brown layer, approximately 250mm thick, probably post-Roman ploughsoil. The lower 200mm consisted of a yellowish-brown sandy deposit with abundant gravels, which was probably natural subsoil. Finds from the spoil included a small undiagnostic fragment of brick or tile and a small modern glass shard (not retained).
