Ozama Fortress
Ozama
The Ozama Fortress, located at the entrance of Santo Domingo's Ciudad Colonial in the Dominican Republic, is a historic stone castle built between 1502 and 1508. It is recognized as the oldest European military construction in the Americas and a UNESCO World Heritage Site. Designed in a medieval style, the fortress features an 18-meter high central tower known as the Tower of Homage, with walls up to 3 meters thick. Originally constructed to defend the city and port from pirates and foreign invaders, the fortress was built using coral stones with cement made from gypsum, clay, lime, and animal blood. Inside, the fortress contains tunnels and dungeons where prisoners, including Christopher Columbus, were held. Over centuries, it served as a military fortification, prison, and later a public building. The site also features a statue of Gonzalo Fernández de Oviedo y Valdés, an important historical governor and author. Its strategic location overlooking the Ozama River and its well-preserved original architecture make it a unique monument to colonial history and military engineering in the New World.
