Fort Tourgis is an extensive fortification in Alderney to the north west of St Anne forming part of the Fortifications of Alderney.
Fort Tourgis, completed in 1855, was designed to accommodate 346 men and was originally to be the largest of Alderney's Victorian forts. It was also designed to mount 33 heavy cannon in five batteries together with four 13-inch mortars. Fort Albert, begun a year later in 1856, was to become the island's largest and most heavily armed fort, but even today Tourgis remains a very impressive structure.
Alderney's Victorian forts were designed to defend the island and its harbour, which was planned to accommodate a British fleet to respond to French naval power in the Channel.
