The remains of a Norman Abbey Church stand in the grounds of St Mary's Abbey, an Anglican Benedicine Nunnery in West Malling.Various parts of the original building still stand, including the western tower, south transept, the south wall of the nave and part of the north wall. The western tower has a square base, becoming an octagonal shape after the third stage, with two flanking towers. Although part of the 11th century scheme, the tower was probably not completed until the end of the 12th century. The apse and 12th century chapel were destroyed by an early 13th century extension to the quire. Later additions and alterations can be seen in parts of the buildings while only traces of other parts are visible.
