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.

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.
