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 Mór, 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 Laisrén mac Nad Froích (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

Castle Coole is one of the most magnificent Neo-classical houses in Ireland set in a 1,200 acre (490 ha) wooded estate. Built in the 18th century, the grand mansion was home to the Earls of Belmore. The 7th Earl Belmore gave the manion to the National Trust in 1951. The house was originally constructed as a summer retreat and cost £57,000, the equivalent of around £20 million today. It is set amongst beautiful parklands dotted with oak, ash and beech trees. Some of the land is given to local farmers to graze their cattle and sheep. You can visit the mansion and its grounds for an insight of how life would once have been for its wealthy inhabitants and their staff. Entrance to the grounds costs £5 per adult.
