Do you know where the great hidden fortress of the island of Menorca is located?

Mahón, August 6, 2026

We are talking about a fortress that was built on the southern shore of the entrance to the port of Mahón in the mid-16th century, following the design of the Italian engineer Juan Bautista Calvi. Its purpose was to defend against the frequent attacks by the Turkish fleet in the Western Mediterranean, which attacked Menorca twice in just over twenty years.

The position of San Felipe Castle facilitated Spanish communications with Italy during the 16th and 17th centuries, and later, during the British occupation of Menorca, it served as a naval arsenal supporting the British colony in Spanish territory, Gibraltar.

Unfortunately, Charles III, and then Charles IV decades later, ordered the castle’s demolition. Today, only the outline of what once was remains. However, its underground galleries, at least in part, were not destroyed and have been restored thanks to the work of the Menorca Military Museum Consortium. San Felipe Castle hides a great treasure underground that is well worth discovering by residents and visitors alike.

Some of these galleries can be visited with a guide, offering an experience that surprises everyone with its uniqueness and beauty.

San Felipe Castle is a piece of Menorcan history that is well worth exploring.
