Fortaleza Ozama, constructed between 1502 and 1508 at the mouth of the Ozama River in Santo Domingo, holds the distinction of being the oldest fortress in the Americas. Built under the direction of master builder Gómez García de Varela and governor Nicolás de Ovando, this coral stone structure in medieval European castle form was designed to protect the colonial city from pirate attacks and invasions by English, French, and Portuguese forces. UNESCO recognized its significance by designating it a World Heritage Site along with other Ciudad Colonial monuments. The Torre del Homenaje features distinctive 2-meter-thick walls with riflemen's embrasures and 360-degree rooftop views over the city. Serving as a prison until 1970, the fortress witnessed pivotal moments in Caribbean history, including the imprisonment of notable historical figures in its dungeons.
