Conquistadors built Panamá Viejo, the first European settlement on the Pacific Coast of the New World, in 1519. The original site was abandoned in 1671 after Henry Morgan’s pirates attacked and the residents relocated down the coast. This second settlement, now called Casco Viejo (old town), is the historic district of Panama City. Together, both locations make up a UNESCO World Heritage Site. At Panamá Viejo, visitors can explore an archaeological site with famous ruins, while Casco Viejo is abuzz with the markets, cafés and nightlife found along its narrow streets and in its classic waterfront buildings.
