The Port, Fortresses and Monuments of Cartagena

UNESCO inscribed the Port, Fortresses and Group of Monuments of Cartagena in 1984, under cultural criteria (iv) and (vi). The property sits in Bolivar Department on the Caribbean coast, and the reason for the inscription is stated plainly in the citation: sheltered inside a bay of the Caribbean Sea, Cartagena has the most extensive fortifications in South America.

That is the thing to hold on to while walking around, because the walls are so thoroughly part of the city's furniture that it is easy to read them as decoration. They are not. They are the reason the city survived to be walked around.

The three quarters

UNESCO describes the inscribed city as divided by a system of zones into three distinct quarters, and the division is still the most useful mental map a visitor can carry:

• San Pedro, holding the cathedral and many Andalusian style palaces. This is the grandest part and the one most photographed.
• San Diego, where the merchants and the middle class lived. Quieter streets, smaller houses, and the better places to eat.
• Gethsemani, described in the citation as the popular quarter. It is the one that has changed most in the last decade and is where a lot of the current life of the city is.

What to see

• The Castillo San Felipe de Barajas. The great hillside fortress above the city, with its sloping batteries and tunnel system. Go early, before the heat.
• Las Murallas. The walls themselves, best walked at the end of the day when the stone has stopped radiating.
• The Plaza de Santo Domingo and the cathedral quarter in San Pedro.
• Gethsemani's plazas in the evening, which is where the city is loudest and most itself.
• The Palace of the Inquisition, for a history the balconies and bougainvillea otherwise soften.

That last point deserves saying directly. Cartagena was one of the principal ports of the transatlantic slave trade in Spanish America, and the wealth that built the palaces came from it. A visit that takes in only the prettiness is a visit that has missed what the city is. The heritage and reconnection guide covers that history and where to engage with it.

⚠ Cartagena and the advisory

This has to be said plainly because it is the most common reason people cancel a Colombian trip. Cartagena is not restricted. The cited advisory does name Bolivar Department, but what it names is the southern part of that department, which is inland and a long way from the walled city. The department is large, the restriction is regional, and reading the departmental name alone is how a perfectly sensible trip gets abandoned. The safety guide sets out the full list and both directions of that error.

Practical points

• It is hot and humid all year. December through April is the drier, breezier half. Walk in the morning and the evening and do something indoors in between.
• The streets inside the walls are cobbled and uneven. See the accessibility guide, which treats the old city as a specific problem rather than a general one.
• On health, the cited public health source records no malaria transmission in the city, and records that the yellow fever vaccine is generally not recommended for travel limited to Cartagena. That is a statement about this city and not about the country, and the entry requirements guide explains the difference between a recommendation and an entry rule.
• Ordinary coastal city caution applies inside the walls, especially at night in Gethsemani.

Colombia's other two inscribed properties covered in this cluster are the Coffee Cultural Landscape and the San Agustin Archaeological Park.
