Roscommon Castle is located just outside Roscommon Town. It was built in 1269 by Robert de Uford, judicor of Ireland on lands he had seized from the Augistinian Priory. The Castle was beseiged by Connaught king Ian O'Connor in 1272. 8 years later it was again in the hands of the English Garrison and fully restored. By 1340 the O'Connors regained possession of it and held it for 2 centuries until 1569 when it fell into the hands of Sir Henry Sidney, Lord Deputy. In 1641, the parliamentarian fraction gained it until confederate catholics underpressed and captured it in 1645. It remained in Irish hands until 1652 when it was partially blown down by Cromwellian Ironsides who had all the fortification dismantled. It was finally burnt down in 1690 and thus it finally fell into decay.
