This collection comprises reports, images, site records, and CAD files from an archaeological evaluation. This was carried out by Colchester Archaeological Trust in June 2020 at St Barnabas' Church, Lamarsh Road, Alphamstone, Essex, CO8 5HS.

The evaluation of two trial-trenches was carried out in advance of the construction of a new shed housing a toilet and a flower arranging and mower storage area with associated services.

The church is thought to pre-date the Norman invasion and to have been built at the site of an earlier Anglo-Saxon minster church. There are several sarsen stones that lie within the churchyard, which lies immediately to the north of the known site of a Roman villa complex. Excavations revealed a possible grave cut, a post-medieval or modern burial vault or funerary monument foundation and a modern pit.

The aim of the evaluation was to determine the potential of the proposed new development to damage significant archaeological remains within the churchyard. Feature, layer and finds numbers used during the current excavation follow on from numbers assigned during the test-pit excavation undertaken at this site by CAT in 2007 (CAT Report 417). One archaeological trial-trench was machine excavated under the supervision of a CAT archaeologist. The trench was 30m long by 1.8m wide.
