San Juan

San Juan is the capital city and most populous municipality in Puerto Rico. San Juan was founded by Spanish colonists in 1521. Puerto Rico's capital is the second oldest European-established capital city in the Americas, after Santo Domingo, and is the oldest European-established city under United States sovereignty. Several historical buildings are located in the historic district of Old San Juan; among the most notable are the city's former defensive walls, Fort San Felipe del Morro and Fort San Cristóbal, and La Fortaleza, the oldest executive mansion in continuous use in the Americas. These historic sites were declared a UNESCO World Heritage Site in 1983. San Juan is Puerto Rico's most important seaport and one of the island's most notable financial, cultural, and tourism centers.
