San Juan was founded by Spanish imperialists in 1521, who called it Ciudad de Puerto Rico (Spanish for "Rich Port City").
Puerto Rico's capital is the second oldest European-established capital city in the Americas, after Santo Domingo, in the Dominican Republic, founded in 1496, and is the oldest European-established city under United States sovereignty.
