An archaeological watching brief took place at St Marys Church, Middle Tysoe, after the floor below the westernmost series of pews had been removed. In 2006, in the area immediately to the west, a previously unknown wall foundation had been found, thought to be from an early tower, along with brick vaults of post-medieval date. The present programme of ground reduction only removed the loose surface rubble and a small amount of compacted rubble from below the floor boards and did not impact on archaeological levels, although a small amount of residual medieval floor tile and other post-medieval material was recovered.
