In the graveyard are several interesting stones, probably the most noted one is known as the Bishops stone, this odd shaped stone has been altered and reused several times, originally thought to have been a carved figure similar to those on nearby White Island. Another stone with a lot of history is the large slab standing west of the bishops stone, one side of the stone bears at least twelve cup-shaped hollows, see image above right, which suggest this maybe a multiple bullaun stone/cup marked stone that has been reused as an early Christian cross slab, as on the obverse face is a Greek cross in a circle with a bifurcated stem. Situated south of the bullaun stone is a holed stone, as the image shows this stone is half embedded in the ground. Immediately to the West of the holed stone is a broken 1.2 metre high stone pillar. This stone may have been damaged. http://www.megalithicireland.com/Killadeas.htm

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.

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.

This fortified house is on Tully Point and built for Sir John Hume who occupied the house until 1641 when it was attacked by John Maguire and burned on Christmas Eve with all its inhabitants massacred. After that it was not lived in again. There is a visitors centre in a restored farmhouse that has an interesting exhibition telling a number of stories relating to the castle. To visit the castle be sure to step off the bike as it is on foot only!

Perched atop a cliff and surrounded by thick forest, it's easy to imagine how life would have been hundreds of years ago as you wander the crumbling walls of Old Castle Archdale. Built in 1615 by Englishman John Archdale, the castle was captured by the Irish in the Irish Rebellion of 1641. The castle was inhabited until 1689, when it was destroyed by fire and abandoned.
