Panamá Viejo is the archaeological site of the original Spanish settlement founded in the early 16th century, making it the oldest European city on the Pacific coast of the Americas. Its ruins, including remnants of churches, convents, and civic buildings, reflect the city’s early colonial history and its destruction by pirate attacks. As part of Colonial Transisthmian Route of Panamá, a UNESCO World Heritage site, it preserves a vital chapter of cultural and architectural heritage, offering insight into the origins of Panama’s urban development.
