The fortress was constructed under the reign of Philip V of Spain to protect the natural harbor of Cala Llonga.
It acted as a strategic observation point for the 'Torres de Defensa' network used to signal threats along the Balearic coast.
The masonry incorporates local 'marès' stone, a porous limestone common in traditional Mallorcan architecture.
Unlike larger castles, this site was specifically designed as a battery for small-caliber anti-ship cannons.
Es Fortí is an 18th-century artillery fortification situated at the entrance of the Cala d'Or harbor in Mallorca. Built in 1730 to defend the southeastern coastline against pirate raids and enemy naval incursions, it serves as a preserved example of coastal military engineering. The structure features thick stone walls and stone embrasures designed for defensive artillery fire. It was partially restored in the 20th century to prevent further degradation while maintaining its original layout. The site remains a publicly accessible historical landmark that offers unobstructed views of the Mediterranean Sea. It is integrated into a modern residential area of the Cala d'Or resort town.

Combine your visit with a walk along the cliff-side path that begins near the fort.
Wear sturdy footwear, as the surrounding terrain is uneven and rocky.
Bring water as there are no amenities located directly inside the fortification walls.
Do not attempt to climb or sit on the historical stone walls, as they are fragile and pose a safety risk.
