La Cabaña is a complex of 18th-century fortifications located on the east coast at the entrance to the harbor of Havana.

The construction of the fortress began in 1763 at the direction of the King of Spain, Charles III. Initially, the construction was controlled by the Spanish colonial authorities, then by the British who temporarily owned Havana. Subsequently, Cuba again passed into Spanish possession as a result of an exchange for Florida. Replacing the earlier 16th-century fortress of El Morro, La Cabaña became the largest colonial military installation in the New World when it was completed (1774).

Currently, the fortress is part of a historical park (together with El Morro), some buildings house museums, including the Museum of Ancient Tools and the Museum-Commandant's Office of Che Guevara.
