A polygonal Roman military enclosure, known from parchmarks and geophysical survey. It is part of the Llanfor Roman military complex (NPRN 95489).
The enclosure is about 125m north-north-west to south-south-east by at most 80m. It is defined by traces of a rampart, fronted by at least two ditches. On the west the enclosure rests against a terrace rising above the river floodplain. On the east it overlies or is overlain by the perimeter of a large marching camp (NPRN 308244). The enclosure's three gates all open on this side. Several features can be made within the enclosure, one likely to be a large granary.
The enclosure has been interpreted as a military stores base.
