Inishmurray may be named after the early saint, Muiredach mac Echdach (fl. early 6th century) of Killala. There are remains of an early Irish monastic settlement. Laisrén (Saint Molaise) Mac Decláin reputedly founded a monastery here in the 6th century. He was confessor of Saint Columba (Colmcille) after the Battle of Cúl Dreimhne on the mainland nearby.
The island's ecclesiastical settlement was attacked in 795 and again in 807 by the Vikings, and eventually the monks abandoned the island and it remained uninhabited until the first secular settlement, probably in the 12th century.
The enclosure wall is impressive - reaching 4.5 metres in height at its highest point and up to 3 metres thick. The site contains various ecclesiastical buildings including enclosures, a stone-roofed oratory, two churches, a clochán, a large beehive-shaped cell, a holy well and other remains including cross slabs suggesting foreign influences. The whole complex is composed of what is probably local sandstone rubble.
References:The Château du Lude is one of the many great châteaux of the Loire Valley in France. Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
