The Roman Fort at Llanio/Bremia

N.G.REFDIMENSIONSAREA
SN643563c.475—500 x c.440 ft

The only historic reference we have of the Roman name for the fort here is contained in the Ravenna Cosmology of the seventh century. In this work, the entry Bremia (R&C#54), which occurs between Gobannium (Abergavenny, Gwent) and Alabum (Llandovery, Dyfed), is considered by scholars to represent Llanio.

The fort's defences consist of a single V-profile ditch 11ft (3.4m) wide and 4ft (1.2m) deep backed by a rampart 18ft (5.5m) wide constructed of turf blocks with a gravel-clay infill. Four phases of timber buildings were identified during trial-trenching in 1969. Pottery fragments indicate a period of occupation 'from c.AD75 to after AD120'. It would appear that the principia was intentionally burnt down in order to reduce the size of the fort, judging from the fact that a (V-profile?) ditch 10ft (3.1m) wide was dug immediately beside the levelled building. Traces of extra-mural industrial activity in the form of 'large deposits of iron slag and ash' were discovered outside the southern defences of the fort. (See: Britannia I (1970) p.269.)

Recent Excavation Work

None of the samian ware recovered in 1972 from the fort (SN644564) could be dated later than c.AD105. During excavations in 1970 the walls of the bath-house (SN644562) were found to be mostly robbed-out, but the tepidarium and frigidarium were both identified. Fragments of window glass and iron T-clamps were found but no dateable evidence was unearthed. Further excavation work was conducted on the east end of the caldarium in 1971, which revealed an apsidal room similar to that found at the baths western end in the previous year. Still no dating evidence was found.
