UNESCO World Heritage
Building began in 1502 on the bluff where the Ozama river meets the sea, which makes this the oldest surviving European military structure anywhere in the Americas. Its centre is the Torre del Homenaje, a square keep with walls more than two metres thick and a flat roof from which the whole river mouth and the colonial city are visible. Around it run later walls, gun platforms and a powder magazine, added as the threat changed from indigenous resistance to European rivals and pirates. The fortress stayed in military use for well over four centuries and served as a prison into the twentieth. Guides wait at the gate and their commentary is most of the value.
History
Governor Nicolás de Ovando began the fortress, recognised by UNESCO as the oldest military construction of European origin in the Americas, and it was built between 1502 and 1508 to the design of the Spaniard Gómez García de Varela, of coral stone, by enslaved Africans and Taíno; in the 16th century its 18-metre Tower of Homage was the tallest European-built structure in the Americas. Sir Francis Drake seized it in 1586, the entrance gate on Calle Damas was built in 1608 and replaced by the present Carlos III gate in 1787, and for centuries pirates and politicians were jailed here. In 1965 it ceased to be a prison and military compound and became a public place (Wikipedia, Fortaleza Ozama).
Highlights
- Torre del Homenaje - the 1502 keep, the oldest of its kind in the Americas.
- The roof platform - the river mouth, the port and the colonial city below.
- The gun batteries - later platforms facing the water.
- Calle Las Damas - the oldest paved street in the Americas, running from the gate.
When to go
November to April is the cooler dry season. Mornings avoid both the heat and the cruise groups. The site is small and takes about an hour unless you take a guide, which is worth doing.
Things to know
Interpretation on site is thin without a guide, and the guides at the gate work for tips agreed beforehand, which is worth settling clearly. The interiors are largely empty stone rooms. Steps and the tower stair are steep with no handrail in places.
Nearby
The Alcázar de Colón is at the top of Calle Las Damas; the cathedral is two streets west.
