Bremia was the Roman fort in Llanio in the Llanddewi Brefi community area. The fort was built by the Romans around AD 75 and was in use to AD 120 in Roman Wales. The fort was situated on Sarn Helen, a Roman road leading north from the fort at Dolaucothi. Five inscribed stones have been found within the fort and surrounding military settlement. Two of these have inscriptions which show the garrison to include to a cohort from the Asturias, northern Spain. Amongst the excavations on the site, is the bathhouse. The bathhouse and fort are scheduled monuments, giving them statutory protection from disturbance.
The only documentary evidence for the name Bremia is a list of place names of the known world compiled in around 700 AD, known as the Ravenna Cosmography. This places Bremia between Gobannium (Abergavenny) and Alabum (Llandovery).
References:Ogrodzieniec Castle is a ruined medieval castle originally built in the 14th–15th century by the W³odkowie Sulimczycy family. Established in the early 12th century, during the reign of Boles³aw III Wrymouth, the first stronghold was razed by the Tatars in 1241. In the mid-14th century a new gothic castle was built here to accommodate the Sulimczycy family. Surrounded by three high rocks, the castle was well integrated into the area. The defensive walls were built to close the circuit formed by the rocks, and a narrow opening between two of the rocks served as an entrance.
In 1470 the castle and lands were bought by the wealthy Cracovian townsmen, Ibram and Piotr Salomon. Then, Ogrodzieniec became the property of Jan Feliks Rzeszowski, the rector of Przemy¶l and the canon of Cracow. The owners of the castle about that time were also Jan and Andrzej Rzeszowskis, and later Pilecki and Che³miñski families. In 1523 the castle was bought by Jan Boner.
