Castillo de los Tres Reyes del Morro (El), Havana

The Spanish raised El Castillo de los Tres Reyes del Morro or Castillo de Morro next to the harbor entrance between 1589 and 1630, with the objective of warding off attacks by pirates and enemy fleets. It has since become one of Havana's most iconic monuments. In 1762, when the British invaded the city, the castle was defended to every last man, for Luis Velasco, who was in command of the besieged garrison, preferred to die rather than surrender. However, local inhabitants are particularly fond of the place thanks to its lighthouse, an addition that was built around 1845.
