It stands on Mount Benacantil (166 m) bordering the sea, which gave it enormous strategic value since from it you can see the entire bay of Alicante and its land surroundings.
In this enclosure we see, among others, the so-called Bastion of the English, as well as other facilities: Engineers Park, Noble Room, which was a hospital, Governor's House, etc.
The intermediate enclosure corresponds to the most important rooms completed in 1580: Felipe II Hall, former Corps of the Troop in front of the large Patio de Armas behind whose back are the ruins of the hermitage of Santa Bárbara, Guard Corps, Baluarte de la Reina, etc.
The lower area where we find the Revellín del Bon Repós dates back to the 18th century, which currently serves as a parking lot and where the monument to the illustrious Alicante soldier Félix Berenguer de Marquina is located, who was captain general of the Philippines and viceroy of the New Spain.
The large white marble shield (18th century) above the access door to the second enclosure was in the Royal Consulate of the Sea, a building destroyed by an explosion.
