Mutton Island

Mutton Island is an uninhabited island and townland off the coast of County Clare, Ireland, about 1.5 km from the mainland. The nearest village is Quilty, which is roughly 3.5 km from the island.

It is used mainly for grazing sheep, and is host to several abandoned houses and two forts.

There is no public ferry service to the island, on which there is no jetty or boat slipway. It contains no roofed buildings, but there is a limited supply of fresh water.

History
The fortifications on the island were likely constructed by Thomas Burgh around 1702.

The island was populated as late as the 1920s and is believed to have been part of the mainland until the year 804.
