Old Castle Archdale sits on a forest clifftop. It is named 'old' to distinguish it from its successor, the 18th century Castle Archdale. The castle was built by an Englishman from Suffolk who had been granted the estate in 1612 after paying 5 pounds, 6 shillings and 8 pence for the 1000 acres of land. During the Irish Rebellion of 1641 the castle was captured by Rory Maguire as part of the uprising to retake his lands that had been lost in 1607. The heir to the castle was saved by his nurse however the other children were killed. After the castle was returned to the family it was repaired and lived in until 1689. The castle saw its end during the Williamite Wars when the castle was burnt out and abandoned.

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.
