The Torreón de la Chorrera, or to give it its full name, Fuerte de Santa Dorotea de la Luna de la Chorrera, was completed in May 1646. The tower stands on a coral islet only a few metres from the shore and not much larger than the tower itself. The tower's purpose was to impede the entry of enemy ships into the mouth of the Almendares River. The British damaged and captured the tower when they took the city in 1762, after which the tower was rebuilt in its present form. Today, the tower contains a restaurant. In 1982, the Torreón was inscribed on the UNESCO World Heritage List, along with other historic sites in Old Havana, because of the city's importance in the European conquest of the New World, its fortifications, and its unique architecture.

The siege of Havana was a successful British siege against Spanish-ruled Havana that lasted from March to August 1762, as part of the Seven Years' War. After Spain abandoned its former policy of neutrality by signing the family compact with France, resulting in a British declaration of war on Spain in January 1762, the British government decided to mount an attack on the important Spanish fortress and naval base of Havana, with the intention of weakening the Spanish presence in the Caribbean and improving the security of its own North American colonies. A strong British naval force consisting of squadrons from Britain and the West Indies, and the military force of British and American troops it convoyed, were able to approach Havana from a direction that neither the Spanish governor nor the Admiral expected and were able to trap the Spanish fleet in the Havana harbour and land its troops with relatively little resistance.
