Tech Entrepreneur's £4 Million Island Fortress: From YouTube Video to Luxury Retreat
2025-08-09
British tech entrepreneur Mike Conner bought a 19th-century island fortress off the coast of Pembrokeshire, Wales, in 2017 for £500,000 after seeing a YouTube video. Four years and over £2 million later, the waterlogged, windowless ruin is now a luxury retreat sleeping 20, boasting a helipad, rooftop bar, games room, and sea-view office. The extensive renovation included a £300,000 investment in renewable energy, making the fortress completely self-sufficient. Now, this meticulously restored marvel is on the market for over £3 million, awaiting its next owner seeking secluded luxury.
