[1] Notably, the tower has an asymmetrical lower level due to its southward extension after the Reformation.

This extension, featuring a nearly 14-foot thick wall, was constructed to support a new belfry, which housed five bells that had been relocated from the dissolved Missenden Abbey.

[2] The church underwent restoration, and its northeast aisle was rebuilt between 1899 and 1900[1] by the architect John Oldrid Scott.
