Sometimes exhibitions are held in these courtyards to display some of the key historical notes of the use of this area during the war.

Like many other castles in the area, Monea Castle was built during the Plantation in the 17th century, when settlers from Great Britain colonised lands in Ireland. The Scottish Reverend Malcolm Hamilton built the castle in 1616 in a distinctly Scottish style. The castle was attacked and occupied during the Irish Rebellion of 1641 and was lived in by the family of colonel Gustav Hamilton until 1704. A few decades later, a fire destroyed much of the castle, leaving it ruined as it is today. The ruins are free to visit and open 9am to 5pm Monday to Friday.
