Spitbank Fort, Sea fort in Southsea, England.
Spitbank Fort is a sea fort in Southsea, England, located about 525 feet (160 meters) offshore in the Solent. The circular structure shows thick granite and brick walls with multiple gun decks facing the open water.
Construction began in 1861 following government plans to counter enemy ships. Completion took until 1878, and the fortification saw service during both world wars before being abandoned in the 1950s.
The name comes from the original sandbank in the Solent that served as its foundation. Together with two other forts, it forms a defensive line that visitors can observe from the water today.
Boat connections from the mainland depend on weather and tides, so checking conditions in advance is helpful. The open-sea location means access may be limited during stormy weather.
The entire facility has been converted into a private hotel with accommodation and dining spaces, open only to booked guests. Those not staying overnight can still view the fort from boats passing through the Solent.
