Since the 1980s, aerial photography has identified over 55 crop-marked enclosures in south Ceredigion and several more in north Pembrokeshire, many of them rectangular in form. As little or no earthwork evidence survives, geophysical and topographic surveys were undertaken in 2004–05 to investigate their character. While surface traces were slight, the surveys revealed significant below-ground archaeology, including circular gullies, hearths, post-holes and internal divisions, strongly suggesting settlement activity comparable to Iron Age defended sites. The distinctive group of rectangular enclosures remains unusual in the region, and their exact date and function continue to be the subject of ongoing research.
