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

Devenish Monastic Site is generally considered to be the most important of Lough Erne's many island church settlements. Devenish was founded in the 6th century by St Molaise. It was raided by Vikings in 837 and burned in 1157, but in the Middle Ages flourished as the site of a parish church and St Mary's Augustinian Priory. There are extensive low earthworks on the hillside, but the earliest buildings are St Molaise's House (a very small church) and the fine round tower close by, both with striking Romanesque decorations from the 12th century. Teampull Mรณr, the lower church, dates from the early 13th century and has a beautifully moulded south window. It was extended to the east in about 1300, while later additions include a residential wing to the north and the Maguire Chapel to the south, with 17th century heraldic slabs. St Mary's Augustinian Priory on the hilltop dates from the middle 15th and early 16th centuries, with church, tower and small north cloister. In its graveyard stands an unusual, intricately-carved cross of the middle 15th century. - https://en.wikipedia.org/wiki/Devenish_Island - https://web.archive.org/web/20120224043140/http://www.culturenorthernireland.org/article.aspx?art_id=746

Founded by Saint Laisrรฉn mac Nad Froรญch (aka St Molaise) in the 6th century, the monastic site was built on a pilgrimage route to Croagh Patrick. As you view the Island from Trory Pier you can see the 25 metre tall 12th century round tower standing majestically above the ruined buildings. The tower has wooden floors and can be climbed by the public via a series of ladders. The tower is decorated with 12th century romanesque features, the most unusual feature is a beaded cornice running around the top of tower with head sculpture featured above the bell-storey windows. - http://www.megalithicireland.com/Devenish%20Round%20Tower.html - https://archive.ph/20121224010315/http://www.ni-environment.gov.uk/places/monuments/devenish.shtml#selection-1091.0-1091.30

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.
