The city of Panama was founded in 1519 and lasted for 152 years before it was destroyed by the pirate Henry Morgan and set alight in January 1671 by Governor Juan Perez de Guzman. To rebuild, Antonio Fernandez de Cordoba then started constructing a new city, which was completed and settled in 1673 and is now known as Casco Antiguo, or Casco Viejo, or San Felipe. The historic district is located on a peninsula, isolated by the sea and defended by a system of walls. It is a World Heritage Site and has been preserved as the original site of the modern city of Panama.
