Portobelo-San Lorenzo

Portobelo is a historic port and corregimiento in Portobelo District, Colón Province, Panama. Located on the northern part of the Isthmus of Panama, it is 32 km northeast of the modern port of Colón now at the Atlantic entrance to the Panama Canal. It has a population of 4,559 as of 2010, and functions as the seat of Portobelo District.Established in 1597 for its deep natural harbor, it joined Veracruz as ports used by the Spanish Empire to ship treasure from the mines of Peru back to Spain. The city was repeatedly captured by British privateers and pirates, culminating in a successful siege by the Royal Navy in 1739, during the War of Jenkin's Ear.

Its economy received a major boost in the late-19th century during the construction of the Panama Canal. In 1980, UNESCO designated the ruins of the Spanish colonial fortifications, along with nearby Fort San Lorenzo, as a World Heritage Site named "Fortifications on the Caribbean Side of Panama: Portobelo-San Lorenzo".
