Santo Domingo, known officially as Santo Domingo de Guzmán, is the capital and largest city in the Dominican Republic. The city is located on the Caribbean Sea, at the mouth of the Ozama River. Founded by Bartholomew Columbus in 1496, it is the oldest continuously inhabited European settlement in the Americas, and was the first seat of Spanish colonial rule in the New World. It lies within the boundaries of the Distrito Nacional (D.N.; "National District"), itself bordered on three sides by Santo Domingo Province.
Santo Domingo was called "Ciudad Trujillo", from 1930 to 1961, after the Dominican Republic's dictator, Rafael Trujillo, named the capital after himself. Following his assassination, the city resumed its original designation. Today, Santo Domingo is the Dominican Republic's major metropolis, and is the largest city in the Caribbean by population.
