Fortaleza de San Carlos de la Cabaña

Enjoy superb views of Old Havana and the harbor, visit museums and attend a cannon-firing ceremony at this huge 18th-century castle complex.

Step back in time to Havana’s colonial years at the Fortaleza de San Carlos de la Cabaña (Fortress of Saint Carlos de la Cabaña). Explore the cobblestone lanes, courtyards, ramparts and tunnels of this village-like complex. Browse museum exhibitions and watch a show featuring actors dressed in period clothing. Fortaleza de San Carlos de la Cabaña sits above the northeastern side of the city harbor and is one of the biggest Spanish-built strongholds in the Americas.

King Carlos III of Spain commissioned the construction of the fortress in 1763 to protect the city from invaders. It holds the honor of never being conquered. The infamous dictators, Gerardo Machado and Fulgencio Batista, operated military prisons here in the 1900s. Note that Che Guevara also used the fortress as his revolutionary headquarters. Some of the 19th-century executions of Cuban patriots were conducted here.

Wander around the well-preserved grounds for a sense of the many historical events that have taken place here. Climb up onto the ramparts, where a series of cannons point out toward the sea. Gaze across the water and over the rooftops of Old Havana. Spot major landmarks such as the Castillo de la Real Fuerza and Havana Cathedral.

Dedicate time to exploring the complex’s museums. See displays of arms, such as cannons, catapults and crossbows, in the Fortress and Weapons Museum. At the Che Guevara Command Headquarters Museum, photographs and personal belongings offer a glimpse into the life of revolutionary leader Che Guevara.

Visit in the evening to witness the daily cañonazo. Observe as performers dressed in typical 18th-century military uniforms signal the end of the day with a cannon salute. During the colonial years, this event warned of the imminent closing of the city gates.

Located in Parque Histórico Militar Morro-Cabaña, the fortress is about a 10-minute drive from Old Havana. Get here by catching a taxi, bus or the yellow rickshaw-like coco taxi. Visit the nearby 16th-century Castillo de los Tres Reyes del Morro as well.

The Fortaleza de San Carlos de la Cabaña is open daily and has an admission fee.
