Fort Tigné
Sliema, Malta · built 1793
Fort Tigné (Maltese: Il-Forti Tigné - Il-Fortizza ta' Tigné) is a polygonal fort in Tigné Point, Sliema, Malta. It was built by the Order of Saint John between 1793 and 1795 to protect the entrance to Marsamxett Harbour. It is one of the oldest polygonal forts in the world. The fort, extensively altered by the British in the 19th century, remained in use by the military until 1979. Fort Tigné was restored in the early 21st century, and it is now in good condition. It has been on Malta's tentative list of UNESCO World Heritage Sites since 1998, as part of the Knights' Fortifications around the Harbours of Malta.
