Situated in West Wycombe Village, on the main A40, High Wycombe to Oxford road about 1 mile from High Wycombe. The Dashwood Mausoleum near the church was built in 1765. It is a vast roofless, hexagonal construction built of Portland stone and flint. It is the final resting place for members of the Dashwood family.

The Church at the top of the hill stands within a 5th Century Iron Age fort which was originally surrounded by a ditch and rampart. In 1751 the origina Norman tower was considerably heightened and was capped with a golden ball which can seat six people. The view from the top of the tower is spectacular. The interior of the church is very beautiful and was copied from the Sun temple at Palmyra near Damascus, which was built in the 3rd century A.D.
