The oldest parts of the existing building are the tower and three bays of the arcades, which are Norman architecture of the early 12th century.
[2][3][4] From 1230 the church was controlled by Maison Dieu, which was built in Dover in 1203 to accommodate pilgrims from overseas visiting Canterbury Cathedral.
[3][5][6] In 1843–1844, during the incumbency of Canon John Puckle, the church, except for the tower, was rebuilt in Early English style.
Windows have been installed since the war to commemorate important relations between the church and the town.
[7] The church houses the main memorial to the victims of the MS Herald of Free Enterprise, which capsized outside Zeebrugge in Belgium on its way to Dover on 6 March 1987.
