For some, the ultimate dream is owning a private island surrounded by unspoilt nature. For others, it is the opportunity to embrace a more self-sufficient lifestyle by farming the land. And for the forward-thinking, it is the chance to secure a sound investment with long-term potential. Mutton Island, Quilty, Co Clare, speaks to all three ambitions.

Situated off Seafield Harbour on the west coast of Co Clare, the history of the 185.5ac island stretches back to the sixth century, when St Senan founded an oratory on the site. Centuries later, in 1588, a Spanish Armada ship floundered off the coast, and according to local legend, sheep from the vessel came ashore, giving the island its name. By the 1700s, its rugged coastline and deep sea caves earned it another role, attracting tobacco and wine smugglers looking to avoid import taxes.

Uninhabited since the mid-20th century when the last of the 12-family fishing community left for the mainland, the island is now a haven for wildlife. It is designated as a wildfowl sanctuary and a Special Protection Area (SPA) under the EU birds directive.

Comprising mainly of good-quality fattening grassland and pasture, the plot also benefits from a freshwater lake and several wells, making it suited to grazing sheep and cattle.

While the ruins of two cottages sit on the eastern side, the island’s protected status may limit the potential for residential redevelopment.

For buyers with farming or investment interests, Mutton Island’s eligibility for a range of various government grants and schemes is likely to be of interest.

With its unusual blend of ecological significance, island seclusion, agricultural potential and investment appeal, Mutton Island presents an interesting opportunity for businesspeople, farmers and conservation bodies. Guided at €1.8m, it is for sale by private treaty with Streets Ahead Properties, Ennistymon, Co Clare.
