The church consists of tower, with spire, three bells, nave, chancel and north aisle.

The north aisle is terminated by a chapel, probably erected by the Grey family of Wilton, whose arms are placed there.

The marble baptismal font, of c. 1200, is south Italian, given to the church in 1909 in memory of Sarah Decima Bradney (died 1907).

In 2014, police raided the Crown Inn to look for the "Holy Grail" which was reported stolen from nearby Weston under Penyard.

The only item found that vaguely resembled the Nanteos Cup was a wooden salad bowl.
