Porth-Egr Promontory Fort was recorded as a possible hillfort by DAT. Aerial photographs (neg. ref. 2002/5020-68, 5th March 2002) clearly show 3 lines of defence cutting off the main promontory. The outermost and middle ramparts are set parallel to one another and cut across the promontory at right angles to the cliff. The innermost rampart is at a diagnonal and appears to have a ditch or quarry pits placed on the inner edge; this may result from a different phase of works.
