San Juan is the capital and most populous city of Puerto Rico, a US territory in the Caribbean, home to approximately 340,000 city residents and 2.2 million in the metro area. It operates on Atlantic Standard Time (AST, UTC-4), fixed year-round without DST. Old San Juan, a UNESCO World Heritage Site, is a stunning 500-year-old walled colonial city on a small island connected to mainland Puerto Rico by bridges — its colourful Spanish colonial architecture, cobblestone streets paved with blue adoquín bricks, and massive fortresses (Castillo San Felipe del Morro, Castillo San Cristóbal) rank among the most intact colonial city centres in the Americas. Puerto Ricans are US citizens but do not vote in US presidential elections and have no voting representation in Congress. The island is the world's largest producer of rum by volume and the birthplace of the piña colada cocktail.
