Torreón de la Chorrera - Credit: Wikimedia Commons
The Torreón de la Chorrera (Tower of 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.
