Walmer is a coastal town 6 miles SE of Sandwich and just over 7 miles NE of Dover. The church of St Mary has a twin-cell form with a tall nave and chancel, and a later porch. A N aisle was added in the 17thc and demolished in 1898, returning the building - the 'unsightly object' seen by Glynne in the mid-19thc - back to its original size. A new church dedicated to St Mary was built nearby in the late 19thc, after which the original church became known a 'Old St Mary's' or St Mary the Blessed Virgin. Features of interest include the chancel arch and the S doorway.
