San Juan is the capital of Puerto Rico and its largest city, with 342,000 (2020) inhabitants in the municipality and 2,203,000 in the metropolitan area. Founded in 1521 by the Spanish conquistadors, San Juan is the oldest city under the jurisdiction of the United States. San Juan is located in the north-east coast of Puerto Rico and features distinctly centuries-old architecture, such as Spanish military forts built from the 1540s to 1800s, an active harbor, and a very active economic area in the Hato Rey and Santurce districts.
