In the book Saints and Stones (ISBN 1-84323-124-7) Davies and Eastham describe the evidence for prehistoric use of the site where the church now stands:
Archaeological aerial photography has shown that the circle of the churchyard is enclosed within a larger defensive bank and ditch which also bounds the farms of Prisk and Temple Druid, previously called Bwlch-y-Clawdd. The earlier name, meaning ‘the breach in the bank’ may derive from the defensive enclosure. It was rebuilt in the 1790s by the architect John Nash for Henry Bulkeley and the name changed to Temple Druid. There are a number of sites in west Wales which have defensive enclosures around the church and surrounding hamlet. They are difficult to date, but most are associated with prehistoric settlements and burials, and with early Christian stones.
