St Martin's Church, Canterbury
Local finds prove that Christianity did exist in this area of the city at the time. The church contains many reused Roman bricks or spolia. It also has complete sections of walls of Roman tiles. At the core of the church the brick remains of a Roman tomb were integrated into the structure. Several sections of walls are clearly very early. It is possible that a blocked square-headed doorway in the chancel was the entrance to Bertha's church. Meanwhile, other sections of wall come from the period after the Gregorian mission in the 7th or 8th centuries. The apse that was originally at the east end has been removed. The tower came much later, in Perpendicular style. The church is a Grade I listed building.
