Clonmacnoise Castle, County Offaly, Ireland
During the period of 1170-1220 the Anglo-Normans began the colonization of Ireland, building Motte and Bailey Castles throughout the island. The wooden castle that stood on the top of the motte at Clonmacnoise was destroyed by fire and later in 1214 the Justiciar of Ireland, Henry of London, built a stone castle on the motte. This was to guard the bridge across the River Shannon.
The castle was destroyed during the Gaelic Resurgence in the late 13th to early 14th century. Originally it had three stories but very little remains of the castle today. The ruins are very dangerous, delicately balanced in a bizarre but fascinating position on the edge of the mound.
