Castle Lyons
Castle Lyons is situated 6 km south of Fermoy near the village of Castlelyons, in a field behind an industrial site off the main road near Castlelyons.
The castle is now in ruins and becoming overgrown with plants. It was once a fortified house with most of the walls over 4 feet thick.
Castle Lyons was one of the main seats of the Barry family in the 13th century, ever since King John granted the land to William de Barry. The Earl of Barrymore took over the castle in 1627 and built a large fortified house. In the 17th century the castle was held by the English as a stronghold against the Irish. Castle Lyons was captured by Lord Castlehaven after the battle of Manning Ford in 1643. The castle remained a habitable building until it was destroyed by fire accidently in 1771.
