The Fortifications on the Caribbean Side of Panama: Portobelo-San Lorenzo form part of the defence system built by the Spanish Crown to protect transatlantic trade.
They are magnificent examples of 17th- and 18th-century military architecture. The forts, castles, barracks and batteries of Portobelo created a defensive line around the bay and protected the harbour; the works at San Lorenzo guarded the mouth of the Chagres River.

Initially when planning our stopover in Panama City (an easy and cheap option with COPA), we had planned to visit the Panama WHS and the Portobelo part of the Portobelo-San Lorenzo WHS, using public transport. But after seeing how easy driving is in the country (a whole swathe of the country was basically part of the USA for years), we decided to hire a car for the day to visit San Lorenzo and the canal.
Visiting San Lorenzo is easier than it used to be, thanks to the building of a new bridge north of Gatun, the Puente Atlantico. It's an impressive bridge to drive across, and there's no toll. Continue down the road past Fort Sherman, past the old military booth where no-one waved us down. The road is now nicely sealed all the way to San Lorenzo, at least when the road works present when we visited in June 2022 are finished.
San Lorenzo itself was also undergoing renovations. There's a new video with a version in English from early 2022 that we watched before wandering around the site, with newish signs in both English and Spanish. We joked that they were preparing the site for sound-and-light shows (about the pirates, of course), as the renovations involved more concrete than we thought was suitable. However, we noticed the restorations at Panama Viejo also involved more modifications than we expected, with signs explaining they were making the new parts distinct from the old.
The fortress by itself isn't that impressive, but if they inscribe the extensions for the overall Trans-Isthmus route, of which both fortresses are part, the WHS has more weight.
Of course we also visited part of the canal. We followed the signs to the new Aqua Clara Locks and its visitor centre nearby, where we watched a huge container ship pass through, before being treated to a huge thunderstorm with lightning that may have hit the ship and enough rain to almost flood the road out. It was sunny by the time we got to the Miraflores Locks, although we skipped paying to visit another set of locks.
We visited Portobelo July 2019 as an easy day trip from Panama City on public transit. There is actually very little to add to the previous reviews as it is the kind of place where nothing changes. If anything it feels even more neglected. Other than a couple of local visitors we were the only ones there, which left us free to sit and imagine days gone by. The natural harbour and its strategic importance is obvious at first glance and at Portobelo there are two little fortifications (Santiago and San Jeronimo) to quickly explore. In a rush it could be seen in 10 minutes but if you are the type that enjoys history unrestored and decaying it is a great place to linger.
Changing buses in Sabanitas makes the journey quick and easy. We decided to go all the way into Colon on the return trip which was a mistake. Although it wasn't far, it easily doubled the journey time because of frequent stops and Colon itself looked very uninviting.
Both sites visited just recently (November 2017) with a rented car as that is the only possibility to reach San Lorenzo castle without participating in expensive organised tours.
From Colon one should folow the signs to Gatun Locks or Agua Clara (which is a new part of extended Panama Canal next to Gatun Locks). So far crossing Panama Canal is possible only through the Locks (althoug a new big bridge over the Canal is visibly going to be built). The passage is occasionaly closed due to ships going through the Canal but the crossing usually does not take longer than half an hour.
After the Locks there is an asphalted road towards Fuerte Sherman (there is a checkpoint where you should tell you are going to Fuerte San Lorenzo). A few km before the castle there is an official entrance to San Lorenzo Protected Area (5 USD per person for foreigners).
The fort itself alhough it was detroyed by Morgan and other pirates looks much better preserved than Portobelo fortifications. Full layout is still visible as well as the moat cut in the rocks. There are excellent views from castle walls (Rio Chagres, Atlantic coast). And because of relative difficulty to reach the site it is substantialy less crowded than Portobelo.
Portobelo and San Lorenzo were Spanish fortifications on the Caribbean coast of Panama. Portobelo even was the most important Spanish port of Central America in its time, the storehouse for the silver and gold that came from Peru by land or sea/river and had to be transported across the Atlantic. Both sites lie on either side of the modern city of Colón, some 80 km apart.
As most others, I only visited Portobelo. I would love to see a review of San Lorenzo on this website too, but it isn’t as easily accessible. Without a rental car, your only chance is to join a day tour from Panama City. The pricing of these tours (of any guided tour from Panama City) is ridiculous: they all seem to start at 100 US dollar. That’s the downside of Panama: due to the cruising public, a large number of western ex-pats, and the general Americanization of the country prices often bear no relation to real costs.
Fortunately, Portobelo can be reached by public transport. It cost me 5 US dollars each way, with a change of buses in the town of Sabanitas. Taking this route, you avoid Colon which has the reputation of a hellhole (though that might be an exaggeration too). Sabanitas is easy and friendly, and Diablos Rojos race by frequently to take you to Portobelo. I wasn’t the only tourist on this bus, nor in the town itself. On approach, you immediately notice the formidable natural harbour, which even Columbus acknowledged. It reminded me a bit of the Bay of Kotor.
There are several fortresses and other military structures around the harbour of Portobelo. One of the most prominent lies in the center of town: the San Jeronimo Fort. It looks quite OK from a distance, maybe weathered but considering its age and Panama’s climate that is no surprise. Upon entering, I noticed there are no access restrictions. Everybody can walk in as they like, and have a party inside (I saw many empty liquor bottles!). The niches are of excellent use for kissing couples. Later on, I saw two caretakers picking up the trash, so there is some form of maintenance after all.
The effects of the flooding of 2011 are still there: about a third of this fort still is flooded. You can only reach the far end by crossing on two well-placed stepping stones. No health and safety standards here! Even the text on the information panel has faded away. But, in spite of all of this, this fort and its setting at the harbour have real charm. Everything shows the effects of time, but that’s more convincing than so many other fortresses and castles on the List which have been overly restored.
On a prime location lies the former Customs Building. Birds have taken over the top floor for their own use, the ground floor houses the city museum which should not be missed. An introductory video is shown about Portobelo’s history. I found it difficult to get online information about the site beforehand, also the AB evaluation is very short and superficial. The site seems to be surrounded with myths. The video emphasizes the role slaves played in its construction. The focus is not so much on the story of the Spaniards and the English, but on that of the local population which is mostly of African descent.
The site has been on the List in Danger since 2012 mainly due to neglect: environmental factors, lack of a maintenance program and polluted water has led to the deterioration of the site. There are even families living in the inner areas of the Santiago de Gloria Castle, though new houses are said to be currently under construction. The town seems to be too far away from Panama City to attract much-needed attention. It's still worth a detour to visit, however.

I just returned form a visit to Portobelo(Feb. 2011) The heavy rains have taken a toll on the whole area. The road to Portobelo, still had several damaged spots that slowed down traffic. The town of Portobelo had had several house destroyed by landslides with loss of lives. The Fort also suffered damage form the landslides. Parts of the wall had collapsed and huge tree trunk were still in the process of being removed. The site was undergoing repair and restoration. All in all, it is a beautiful site to visit.
(Nb. This review is of a visit in Apr 1991 and submitted to this web site even before it started maintaining submission dates - i.e before 2005!!)
Panama has quite a lot going for it as a tourist destination – excellent bird watching and diving, the San Blas Islands (run as an autonomous province by the indigenous peoples), several colonial historical sites plus the incomparable Canal (which is not a WHS but should be even though it is not even on the Tentative list). If you have time it IS worth the detour to go the 50kms from Colon to Portobelo. This sleepy village was at one time a pivotal location within the Spanish Empire for the transport of gold to Europe, lying as it did at the Atlantic end of a stone highway from Panama City.
I quote :- “Portobelo was the port of entry and of exit for all of South America. The exchange of merchandise took place annually at Portobelo in the form of a fair which lasted from 30 to 60 days. During this time, this sleepy little place was a beehive of activity. Transactions frequently totaled from 10 to 12 million gold pesos. These fairs took place once each year until 1738 when, as a result of continual attacks by pirates, Spain was forced to abandon the Isthmian route for the longer but more secure one around Cape Horn. The frequent pirate attacks forced the Spaniards to adopt a convoy system. Each year two fleets of 40 to 70 ships sailed from Spain, one bound for Veracruz, the other for Portobelo. The arrival of the fleet signaled the opening of the great fair."
For the English (and perhaps for others too) this spot has the added interest of being the burial place for that well known “state supported” pirate Sir Frances Drake (he who “singed the king of Spain’s beard”)! In 1596, after a failed expedition to cross the Isthmus and raid Panama city for the gold which had been collected there for transportation to Europe, he died of dysentery and was buried at sea in a lead coffin.
As you will see from the photo, the ruins of the fort (then the height of military sophistication) are quite well preserved and the situation of the port among green islands and hills is very pleasant. Just relax, let your mind wander and try to imagine those far off days and the impact this place had on world history .
