Fortaleza de San Carlos de la Cabaña spreads across the ridge on the eastern side of Havana Bay, facing Old Havana across the harbor channel. Spain built it between 1763 and 1774, after British forces captured the city in 1762, and it remains one of the largest colonial fortresses in the Americas. Most visitors come for the nightly cañonazo, a cannon shot fired at 9 p.m.
Inside the walls, deep dry moats, massive limestone ramparts and cobbled parade grounds lead to bastions lined with old artillery. The Museo de Fortificaciones y Armas displays weapons and armor from the colonial era. The Comandancia del Che preserves the office Ernesto “Che” Guevara used in 1959, when La Cabaña held political prisoners after the revolution. Each evening, soldiers in 18th-century uniforms march by torchlight to fire the cannon. The shot revives the colonial signal that once announced the closing of the city gates. Every February the fortress also hosts the Havana International Book Fair.
Visitor Highlights & Practical Info
Arrive by late afternoon to explore the museums in daylight and watch the sun set over the Malecón from the ramparts. Then claim a spot near the cannon by about 8:30 p.m., since crowds build quickly, especially from December to April. The evening ceremony usually requires a separate ticket, so confirm current hours and fees at the gate. From Old Havana, taxis reach the fortress through the harbor tunnel in minutes. You can also take the Casablanca ferry and walk uphill. Pair your visit with the Morro Castle next door.
