Archaeological investigation was undertaken by Colchester Archaeological Trust at St Nicholas’ Church in January 2019 in advance of underpinning works.<1> One test-pit was observed by CAT, dug against the west wall of the nave and the southwest buttress of the church. It measured 1.5 x 0.6m in size and was excavated to a maximum depth of 1.1m below the current ground level. It partially overlapped with the position of TP1 excavated in 2005 (CAT Report 350).<1><2> Excavation occurred through two layers. A modern topsoil (L1, c.0.2m thick) sealed L2, interpreted as a working layer, probably deposited during repair work to the church post-1884. The foundations recorded in the test-pit were similar in composition to the foundation observed in the 2005 evaluation (CAT Report 350): a uniform vertical face of Kentish Ragstone bonded in lime mortar. Two small fragments of peg-tile were also observed within the foundations fabric. The full depth of the foundation was not reached in the test-pit, but it is known to be 1.35m deep based on previous investigation. These appear to be the original 15th-century foundations of the building. The uniform foundations in this location also suggest the south-west buttress is original to the building.<1><2>
