Iskaheen The original name of Iskaheen in Muff parish is Uisage Chaoin - "pure waters" - because of a holy well near an ancient church, formerly situated in the area. The Historian O'Donovan supposed that Eoghan (Owen), son of Niall of the Nine Hostages, was buried nearby. The name Inishowen is derived from this Owen. Owen's son is said to have drowned in the Foyle and to have been brought here. The place then became very precious to Owen, and St. Patrick later had a church built there. Also in Iskaheen is the "Giant Stone," locally known as the "Morton God." It is a collapsed dolmen or an ancient burial place, thought to be the biggest in Inishowen. Such monuments were used as graves for chieftains and also as "altars" for pagan worship.

Further north in Ture, at Leper's Point, concrete slabs mark where the U.S. Naval Air Service Station was sited in 1918. Still in Muff is the townland of Ardmore, site of a 7 feet high standing stone, one of the best examples of such monuments in the north of Ireland as both concentric rings and cup-markings can be seen on it. There is also a very big earthen rathwhere there was probably a wooden dwelling-house in the middle ages.

A detour from Muff to Lisnagra wood is well worth while, not only for a walk in the lovely natural mixed wood, but also for the many beautiful views along the way.
