St. Govan's Chapel is a chapel located at St. Govan's Head, Pembrokeshire in south west Wales. Built into the side of a limestone cliff, the building measures with walls constructed from limestone, and consists of two chambers, one in the front and one in the back. The majority of the chapel was built in the thirteenth century, although parts of it may date back further to the sixth century when Saint Govan, a monk moved into a cave located on the site of the chapel. One legend suggests that Saint Govan is buried underneath  the chapel's altar, located at the east end of the building. The entrance to the building is via. a doorway on the north side, low stone benches run along the north and south walls and an empty bell-cote is located at the west end.

Under the chapel is a huge cave system, Ogof Gofan, containing a "cathedral-like structure", but accessible only by means of abseiling down the cliff face. The cave was re-discovered only in 1966, but it had been used by people for thousands of years, when the sea was miles away from the cave mouth.
