Dynamic Panama City boasts a shimmering skyline, cobblestone streets lined with rooftop bars, and centuries of intact ruins to explore. Founded in 1519, the original Panama City – Panamá Viejo – was abandoned in the mid-17th century and replaced by a historic district -- Casco Viejo – that are together recognized as a UNESCO Cultural World Heritage site. Discover a trove of artifacts and information on the planning, construction and operation of the ‘Big Ditch’ at the interactive Panama Canal Museum, and pay homage to the 22,000 workers who died building it at the Plaza de Francia.
