The castle was commissioned to protect the island's trade and local inhabitants from frequent attacks by English and Barbary pirates.
It is frequently referred to as the 'Torre de San Buenaventura' due to its distinct defensive tower design.
The structure is built using local volcanic stone, which was a common material for Canary Islands military architecture during the 18th century.
The castle was declared a Spanish Historical Heritage site in 1949.
Castillo de San Buenaventura is a circular stone fortress located on the eastern coast of Fuerteventura. Built in 1749 by the military engineer Claudio de Lisle, the structure was primarily designed to defend the bay of Caleta de Fuste against pirate raids. It is officially classified as a Bien de Interés Cultural, recognizing its significance to Canary Islands heritage. The site features a defensive ditch, a drawbridge, and massive volcanic rock walls designed to withstand artillery fire. While the interior is not always accessible, the exterior provides a clear view of the historical fortification techniques used in the 18th century. It remains one of the few surviving coastal towers of its kind on the island.
