Thorne Island, a historic coastal landmark, has been a prized possession for centuries. Originally built as a fort in 1852 to protect Milford Haven from Napoleonic invasion, it has since been a hotel and family home. The island, which extends to approximately 2.49 acres, boasts a Grade II* listed coastal fort at its heart and offers a secluded, private property with outstanding panoramic coastal views. The current owners have completed a meticulous restoration project, enhancing the accommodation, installing renewable energy systems, and completing cliff stabilization works. The property totals over 8,000 sq ft, featuring five bedrooms, five bathrooms, workshops, and storage rooms. With its unique location, commanding a prominent position at the entrance to Milford Haven, the island presents an exciting opportunity for a private lifestyle or commercial venture. It can be accessed by sea or air, and the property benefits from five private sea moorings, a private jetty, and a 10m hydraulic crane for boat and supply lifting.
