Fort Marlborough

Fort Marlborough is an 18th-century fortress located on the southern side of Maó harbor in Es Castell. The structure was carved directly into the rock and features thick stone walls, a heptagonal central design, underground tunnels and passages, and gun positions from which defenders could overlook the harbor.

The fortress was constructed by the British between 1710 and 1726 to protect Maó harbor and control access. During 18th-century conflicts, it was damaged by Spanish attacks in 1782 and later rebuilt by the British between 1798 and 1802.

The fortress is named after a British military leader from the early 18th century and stands as a reminder of colonial rule on the island. The place shows how British occupation shaped Menorca's appearance and architecture, visible today in house designs and coastal defense structures.

The fortress is easy to reach by car with parking available, or you can walk from Es Castell or take a bus from Maó. The pathways are flat and easy to navigate, offering free access to explore the exterior and viewpoints.

Inside, visitors find an exhibition showing siege scenes with actors dressed in period costumes using special effects to bring to life how soldiers lived and fought here. This reenactment makes history tangible and helps imagine daily life of the defenders.
