During WW2 Castle Archdale was a major base for flying boats and housed up to 2,500 people. Buildings such as these would have been a central location for the RAF fighters who lived here. Sometimes exhibitions are held in these courtyards to display some of the key historical notes of the use of this area during the war.

Beautiful views over Lough Erne toward Tom's Island. Tom's Island is actually no longer an island, but once was before the lough was lowered.

Take in the fabulous views of Lower Lough Erne from this point. Directly ahead you will see Crevinisaughy and Inishmakill island. These are one of the many islands found in this large lake system that is in fact widened sections of the River Erne as it flows towards the Alantic.

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.
