A stunning 19th-century fort on its own private island - located off the coast of Pembrokeshire, is up for sale - and could be yours for £3million.

The Grade II-listed building on Thorne Island, was constructed in the 1850s to protect against a feared Napoleonic invasion.

It was sold for the first time in 1932 and has since served as a hotel and family home - offering a "haven providing peace, privacy, and outstanding panoramic coastal views".

The island the fort sits on is only accessible by boat to a private jetty, or by air to a helipad, and is just three nautical miles away from the popular seaside town of Milford Haven.

The property is currently enjoyed as a family home, and has recently undergone an "extensive" and "carefully planned" restoration project.

This has included the completion of a rooftop bar; the incorporation of renewable energy services, including underfloor heating; and the installation of a 10m crane for all "boating and daily supply needs".

The home also boasts five bedrooms, three of which are ensuite, an open plan reception and kitchen, a glass-fronted office, and hardwood heritage glazed sash windows throughout.

Outside, there is a courtyard with a sheltered entertaining space and steps to a helipad and roof top bar - as well as a surrounding area filled with caves, "excellent" fishing spots, sandy beaches, and an "abundance of water sport opportunities".

While the property is currently a family home, it is also a registered Hotel & Premises, meaning it also has potential for commercial buyers.

The fort is listed with Strutt & Parker, who have described the home as "an adventurer's paradise".

They said: "Thorne Island presents an exciting opportunity to purchase a spectacular property located off one of the most beautiful coastlines."
