The church of St Davids sits below and to the east of the triangular summit of a prominent coastal hill which has been suggested as a possible Iron Age hillfort by the Dyfed Archaeological Trust, citing both its general shape and the presence of Bronze Age finds just below the summit.

Royal Commission aerial photographs of the hilltop taken during the drought summer of 2013 (on 12th July) appear to clarify parched banks and ditches of a large triangular or pear-shaped hilltop enclosure, generally following the lines of present field boundaries and walls but of more massive construction, suggesting a prehistoric origin. This main hilltop enclosure measures approximately 278m x 110m, enclosing 2.7 hectares. On the east side of the ridge is a discrete, smaller rectangular earthwork enclosure within the larger one, following the line of the ridge but with a rounded southern end, into which the cemetery of St Davids Church encroaches. It is possible that this is also a prehistoric or early medieval enclosure, perhaps representing a first phase, or a contraction of a larger site. Recorded during RCAHMW aerial reconnaissance (frames AP_2013_2951-53) and also during winter conditions on 26th February 2014, highlighting the earthworks (frames AP_2014_0311-12, 319, 324-5).
