Bremia is the name of the Roman fort in the small dispersed settlement of Llanio, West Wales.

[1] This places Bremia on the route that runs from Gobannium (Abergavenny) through Alabum (Llandovery) (see map below).

[2] The almost square enclosure, with characteristic rounded corners, measures some 130 metres (430 ft) across, and could have garrisoned some 500 soldiers.

[2] During the late 1960s and early 1970s a number of excavations were made at the site of the bathhouse, which revealed foundation trenches although the building materials had been removed, and no firm dating evidence was found.
