Origins
The Cartagena that took off in the 1980s did not emerge from nothing: it was the result of a city that had spent decades looking toward the sea and outward. The economic pulse had moved to Bocagrande and El Laguito, where apartment buildings grew one after another on the sand. The tourism boom and construction money drew a city of two speeds: one walled that was being restored slowly and another modern one rising in a hurry.
That same year, 1980, the entire country looked to Cartagena because the Declaration of Cartagena was signed here, the document that created the Contadora Group and put the city in international headlines. Politics and tourism crossed paths in a decade that many remember as the golden era of luxury hotels, private clubs and terraces facing the Caribbean. But the party had a flip side: the abandonment of properties in the center, the closure of mansions that traditional families sold or left adrift, and urban growth that did not always respect heritage.

From that tension between splendor and decay comes the theme of this tour: the modern ruins of Cartagena. We are not talking about colonial vestiges, but about 20th-century structures that were left halfway between boom and oblivion.
Timeline or historical milestones
To understand how we arrived at the ruins that are photographed today, it is worth ordering the milestones that marked the transition from the Cartagena of the 80s to the city of today.
- 1980: Signing of the Declaration of Cartagena in the Centro Histórico, with which the Contadora Group was created. The city enters the continental diplomatic agenda.
- 1984: UNESCO declares the Port, Fortresses and Group of Monuments of Cartagena de Indias a World Heritage Site. A wave of restoration of convents, walls and manor houses begins.
- 1980s and 1990s: Construction boom in Bocagrande and El Laguito. Hotels, apartment towers and commercial spaces multiply facing the sea.
- 1990s and 2000s: Several properties in the Centro Histórico are left without maintenance due to inheritance disputes, bankruptcies or owners' disinterest. The first ruined houses visible to tourists appear.
- 21st century: Restoration of the center advances, but coexists with abandoned properties that become a focus of risk and, at the same time, an object of desire for urban photographers.
The lesson of this timeline is clear: the Cartagena ruin is not an accident, it is the result of economic decisions and difficult inheritances. And like all ruins, it has its own beauty and its own danger.
Key figures or events
There are names that neighborhood memory repeats when talking about the Cartagena of the eighties. The first is that of the builders who raised Bocagrande against all odds, those engineers and architects who bet on a vertical city facing the sea. They were not always famous names, but their work was: the art déco and modern buildings that today coexist with more recent towers.
The second collective figure is that of the fortification workers. The history of the Casa Negra, popularly known as the Boca del Infierno, recalls the galley forced laborers, prisoners of war and enslaved people who built the city walls with their blood. That story, spread in documentaries and local chronicles, is the root of the name that guides use today when they speak of the old Boca del Infierno neighborhood. It is a harsh memory, and it should be told with respect: it is not a horror myth, it is a history of forced labor.
The third key event is the UNESCO declaration itself in 1984, which changed the city's relationship with its heritage. From then on, restoring stopped being a luxury and became a legal obligation and a business opportunity. Many mansions were saved; others got caught in paperwork and are modern ruins today.
Current state
Today Cartagena is a city that learned to live with its scars. The Centro Histórico is more restored than ever, but there are still abandoned properties that generate concern. The local press has documented the risk of ruined houses for tourists and residents, and the authorities have intervened in some properties for safety reasons.
Bocagrande preserves buildings from the 80s with art déco and modern facades that still stand, some restored and others with the charm of the passage of time. The Centro Histórico offers mansions with wooden balconies, interior courtyards and carved gates that can be seen from the sidewalk. And the memory of the Boca del Infierno remains alive in the stories of the guides and in the documentaries that trace the history of the Casa Negra.
La Boca del Infierno (Casa Negra)
La Boca del Infierno is the name that popular memory gave to the Casa Negra, the place where, according to local chronicles, the galley forced laborers, prisoners of war and enslaved people who built the fortifications were crowded together. It is not a place of invented legend: it is a real and bitter chapter of Cartagena's history. Today it is approached from historical narrative and guided tours, not as a horror attraction. Those who want to go deeper can ask the guides of the Centro Histórico about the chronicles of the Casa Negra and look for the documentaries available online.
Ruins and abandoned houses of the Centro Histórico
Walking the Centro Histórico is to come across beauty and ruin on the same block. There are mansions with balconies falling apart, gates closed with chains and courtyards visible from the street. The local press has warned about the danger of these properties, so the rule is clear: they are photographed from outside. The best hours for light are early morning and at sunset, when the sun hits the facades from the side.
Bocagrande: hotels and art déco buildings of the 80s
Bocagrande is the open-air museum of modern Cartagena. There, apartment towers, hotels from the 80s and art déco facades that resisted the passage of time coexist. Some buildings were restored and others show the wear of saltpeter and the breeze. The tour is done on foot along the main avenue and the streets parallel to the sea; the facades can be seen without needing to enter. Caribbean light changes quickly, so it is worth bringing a camera and patience.
Marbella and the route of photogenic ruins
Marbella, north of the Centro, is another point on the route. There you can see residential buildings from different eras and some structures that were left half-built. The walk from the Centro to Marbella allows you to see the contrast between the walled city and the modern one. There is no official ruins tour, so the sensible thing is to go with a local guide who knows the area. For photographers, the key is in the details: grilles, balconies, tiles and textures.
How to explore these sites safely and legally
Urban exploration in Cartagena has unwritten rules that should be followed. First, never enter an abandoned property without authorization: in addition to physical risk, there can be legal problems. Second, walk accompanied and during the day; tourist areas are safe, but not all streets are at any hour. Third, hire certified local guides, who know the history and safe routes. Fourth, carry only what is necessary and do not display valuables. Fifth, respect the communities: many of these houses are in inhabited neighborhoods.
If you want a guided experience, ask about the photographic walks organized by guides from the Centro Histórico.
