The Roman fort at Loughor was founded in c75 AD and occupied continuously until the early 120s. It was then reduced, used sporadically until c150-160 and occupied again from c270 until the early-4th century. Excavation was concentrated on the defences and part of the interior. Examination of the defences has allowed construction methods and metrication to be reviewed. In the interior of the Flavio-Trajani fort, a sequence of granaries, the last associated with charred grain, was followed by a series of four praetoria. Analysis of the data from these buildings has allowed a reconsideration of the form and function of Commander’s Houses in auxiliary forts. Full reports are provided on: coins (S.H.
