Spitbank Fort

Constructed in the 1800s and decommissioned around the '50s, Spitbank Fort is a unique, 33,000-square-foot piece of military history turned boutique retreat. Fully renovated over the past 12 years of consistent ownership, the spartan outpost was transformed into a property with nine guest suites, a bar, a restaurant, a wine cave, a rooftop terrace with a hot tub, and a sauna, among other amenities. The property is as well-suited to be a private fortress as a functioning business, and sits a 15-minute boat ride from Gunwharf Quays, with London just a short commute away. It and its 99,000-square-foot sister island, dubbed No Man's Fort, will be auctioned by Savills on June 18th.
