Fortifications on the Caribbean Side of Panama: Portobelo-San Lorenzo was inscribed in 1980 under criteria one and four, as a serial property. It is two places rather than one: the bay and batteries at Portobelo, and the cliff fort of San Lorenzo standing over the mouth of the Chagres river about eighty kilometers west.
⚠ It is on the List of World Heritage in Danger
The property was placed on the List of World Heritage in Danger in June 2012, and it has not come off. The reasons recorded against it are environmental decay, uncontrolled development around the monuments and the condition of the masonry itself. That is the property's current status, not a historical note, and a visitor should know it: what you are looking at is a World Heritage site that the Committee considers to be at risk, which changes how it feels to stand in it.
Going is not the problem and is arguably part of the answer. Going respectfully, with a local guide, spending money in the town rather than only in the bay, is the version of this visit worth making.
Why here
For close to two hundred years the silver of Peru was shipped up the Pacific coast, carried across the isthmus by mule and loaded onto the treasure fleets at Portobelo. The town held one of the great fairs of the Spanish empire, for a few weeks a year, and was a small malarial bay for the rest of it. That made it the richest target in the Americas, and it was sacked accordingly: Francis Drake died offshore and is buried somewhere in the bay; Henry Morgan took it in 1668; Admiral Vernon took it in 1739 and the news was celebrated in London so loudly that a street was named for it. San Lorenzo guarded the other route, the river, and was taken too.
What to see
- The batteries at Portobelo. Santiago and San Jeronimo sit right on the water, with their gun embrasures still facing the bay. You can walk them freely.
- The Real Aduana. The royal customs house on the square, where the silver was counted, restored and holding a small museum.
- The Church of San Felipe. Home of the Black Christ, the Nazareno, which is the focus of one of the largest pilgrimages in the Americas each October. See the festivals guide.
- Fort San Lorenzo. A separate trip, reached through the former Canal Zone forest at Sherman, and worth it for the position alone: a walled fort on a cliff above the river mouth with howler monkeys in the trees on the approach.
Practicalities
Portobelo is about two hours from Panama City by road and is an easy day trip, better as an overnight if you want the town rather than the forts. It is hot, humid and very green. San Lorenzo needs its own half day and a vehicle.
Portobelo is in Colon province, and the cited health source records malaria transmission in Colon among the provinces where it occurs, so bite avoidance applies here. See the travel safety guide. The town is also the home of Congo culture, which is a subject in its own right and has its own page: the Congo coast guide.
