History
Fort Karl is a historic military fort in Gustavia, Saint Barthélemy, France, built by the Swedes in 1789 during the island’s period of Swedish rule. It protected Gustavia’s harbor and valuable salt industry from attacks approaching from the south. The fort formed part of a defensive system of three forts around Gustavia, alongside Fort Gustav and Fort Oscar.
Swedish rule
The fort was named for Karl XIII, the brother of Swedish King Gustav III. Karl later became king of Sweden, reigning from 1809 to 1818. Fort Karl’s position reflected the strategic importance of Saint Barthélemy and allowed the Swedish authorities to help defend the harbor and its commercial resources.
Ruins and preservation
By the late nineteenth century, Fort Karl had fallen into ruins. The site entered the possession of the Conservatoire du littoral, a French public institution that acquires and protects coastal land, in 2007. Some remains have since been restored, and local preservation is managed by the Saint-Barthélemy Nature Reserve. The site is protected.
Remains
Fort Karl occupies a small hill approximately 34 meters high in southwest Gustavia. The ruined fortification overlooks Gustavia and its harbor to the northeast, while Shell Beach lies to the southeast. Only parts of the former fort survive, and a stone staircase provides access to the site. The elevated position extends toward the surrounding islands of Saint Kitts and Nevis, Saba, Sint Eustatius, and Saint Martin.
