Fort Carl, situated strategically between Gustavia and Shell Beach, now exists only in its foundations, yet its historical significance remains profound. Built in 1789 and named after Duke Carl, brother of King Gustaf III of Sweden, this fort was a crucial part of St. Barth’s defense system during the Swedish colonial period. Its location was carefully chosen to protect against attacks from the south, via the picturesque Shell Beach, and to complement the existing Fort Gustaf. Despite its strategic importance, Fort Carl was modestly manned, often with only four soldiers, which proved insufficient when faced with larger forces.
This was evident in 1807 when a 100-strong French force from Guadeloupe easily overwhelmed the fort, though they only managed to besiege Gustavia for a day. The fort’s defenses were never particularly robust, boasting only two cannons and a small guardhouse that quickly deteriorated. By 1844, reports to Sweden confirmed that no buildings or even a flagpole remained at the site. Today, visitors can see only traces of the powder magazine and paved courtyard. However, the location still offers breathtaking views of Shell Beach and Gustavia, providing a glimpse into the strategic thinking of the island’s past rulers and the challenges they faced in defending this valuable Caribbean outpost.
