A trench was dug by contactors to investigate the cause of subsidence in the north-west corner of the nave of the C15 church, and recorded by Colchester Archaeological Trust. The 1.55m-deep trench exposed intact stone foundations beneath the north and west return walls. At the junction with the tower, the stone foundation had been removed and placed with modern brickwork as part of the reconstructed works following the 1884 Essex earthquake. No early floors were found. Two layers of modern tile flooring and underlying mortar occupied the uppermost 25cm, beneath which was a disturbed soil which extended to the natural subsoil.<1>
