The British and French reinforced this position by the harbour outlet, but the present fortress was built by the Spanish in the 1850s. Artillery advanced in that era faster than castle-building, so although it could serve as a military base and gunnery position, the fortress could not have withstood fire. Nobody did fire on it so it's in good condition.
The Isabela II Fortress or La Mola Fortress is a Spanish military complex located on the Mola peninsula, at the entrance to the port of Mahón, on the island of Menorca, opposite the castillo de San Felipe, which protects the entrance to the port from the other side of the mouth. Next to this fortress is the easternmost point of Spain.

Destilerías Xoriguer
This gin distillery was established in the 18th century and also makes liqueurs. The guided tour includes a tasting. The shop is open all year.
Hospital Island
It has a 6th century basilica, but the mosaics have been taken to Maó town museum. A hospital was built by the British in 1711 and remained in use until 1964 when one was built in town. It's been restored and now hosts an art gallery (Galería Hauser) and botanic garden. Get there on the yellow catamaran from the harbour.
