Summary

This coastal promontory enclosure is situated on the E end of Mutton Island at 'Coonnaluinga Cove' off the W coast of Co. Clare. It occupies a triangular headland that barely projects SE from the Island at an altitude of 4m OD. it is not depicted as a fortified headland on any edition of the OS six-inch maps but is marked as the location of 'Port Tobacco Cave' on the first edition (1842) map. Samuel Lewis, writing in 1837 gives this account of Mutton Island: 'On its shores are some curious natural caves, formerly used by smugglers for storing contraband goods'. He describes the island as containing '210 statute acres of excellent land for feeding oxen and sheep, particularly the latter; hence the name "Mutton Island" from the fine flavour of the mutton'. The small headland is enclosed by an L-shaped earthen bank and external ditch measuring 34.8m in overall length and enclosing a small area of no more than 0.03ha. A possible rectangular structure, measuring 9m NE-SW by 7m NW-SE, is recorded immediately outside the enclosure at the angle in its perimeter, while a later field boundary bisects the interior from NNE to SSW. There are no other recorded internal features and the site is currently under pasture. The satellite imagery gives the impression of a rectangular enclosure that has lost its E and S sides to erosion of the cliff-edge

Investigation History

The site is not depicted on any edition of the OS six-inch maps. Island mentioned by Samuel Lewis in 1837 while T.J. Westropp, the antiquarian and surveyor, visited the island several times. According to the "Annals of the Four Masters" the island was once called Fitha Island and it formed part of the mainland until the day "the sea swelled so high that it burst its boundaries, overflowing a large tract of country, and drowning over 1,000 persons." This happened on March 16th, 804. Some reports describe it as an earthquake, others as a tidal wave when "the sea divided the island of Fitha into three parts." These three islands are Mutton Island, Inismattle (or Illanwattle) and Roanshee (or Carrig na Ron). There is a fourth island in the area called Carraig Aolacan.
