1. PEN Y GAER, DERI ODWYN, Llanbadarn Odwyn. Hillfort. SN 6399 6083. (0.41ha).

Oval hillfort, c.97m x 50m, much reduced by ploughing and mutilated by a disused quarry on the south side. Hogg (Cardiganshire County History 1994, 259-260) notes earlier reference to a wide-spaced outer enclosure which cannot now be traced. He also noted that in 1955 the north rampart survived to height of nearly 2m. Potential ancient fields, radiating out from Pen y Gaer and bisected by the Roman road on the east side, first noted by T. Driver on the basis of map evidence (see NPRN 403444). Visited 1st October 2000.

2. Aerial photography on 27 July 2006 showed cropmarks of plough-levelled bivallate ditches on the east and north-east side of the fort, extending the width of the defences here by a further 30m out from the surviving univallate earthwork.
