The Untold Map of Bogotá Beneath Your Feet
While traffic jams roar on Carrera Séptima and the eastern hills are painted grayish-green by the rain, there exists another Bogotá that few take the time to look at: the one beneath the cobblestones. I'm not talking about TransMilenio stations or the basements of shopping malls. I'm talking about colonial tunnels that connected convents, commercial passages that were the financial heart of the city, and bunkers built during the Cold War under a park that families visit on Sundays.
This guide is not for the tourist who just wants the photo at Plaza de Bolívar. It's for those who wonder what's behind that rotten wooden door on a cobblestone street, for those who get chills passing by a huge drain, and for those who believe Bogotá only has history upwards, towards the hills. The real history, the one that doesn't appear on postcards, is downwards. And in August 2026, much of that world remains intact, waiting for those who know where to knock.

Here is the untold map, with real names, verifiable addresses, and tips that no conventional tour will give you.
1. Tunnels of La Candelaria: From Colonial Refuges to Treasure Legends
La Candelaria is not just the most photographed colonial neighborhood in Bogotá. Beneath its cobblestone streets runs a network of tunnels that connected churches, convents, and elite houses since the 17th century. Official history says they served so priests and nuns could move unseen. Unofficial history, told by guides in hushed voices, speaks of hidden treasures, escapes from the Inquisition, and tunnels that reached the San Francisco River, now channeled under Avenida Jiménez.
The most famous and accessible one is found at the Casa de los Derechos del Niño, on Calle 12b with Carrera 2a. This building, which was a convent of the Order of Dominicans, preserves a section of tunnel open to the public. Don't expect a catacomb lit with LED lights: it's a narrow passageway of brick and stone, smelling of damp earth. It can be visited with prior reservation, and the tour lasts about 40 minutes. The cost is symbolic, around $15,000 COP per person, and the money goes towards the maintenance of the place.
Another key spot is the Museo de la Independencia – Casa del Florero, on the corner of Plaza de Bolívar. In its cellars, remains of tunnels connecting to the Catedral Primada have been found. They aren't always open to the public, but in recent years, special guided visits have been enabled during the cultural week in July. If you can't coincide with those dates, you can see a model of the tunnel system in the museum's temporary exhibition hall.
The Legend of the Cathedral Tunnel
The elders of La Candelaria tell that a secret tunnel connected the Catedral Primada with the old Cementerio Central, crossing under Plaza de Bolívar and heading north. The idea was that archbishops could be buried in secret or that the church's valuables could be moved without being stolen by pirates plaguing the Caribbean coast. No one has officially confirmed that this tunnel exists, but in 2018, during maintenance works on the Plaza, workers reported finding a deep cavity that didn't appear on the plans. The works were quickly covered up, and an archaeological excavation was never carried out. Urban legend or hidden truth? The decision is yours.
2. Forgotten Commercial Passages of the Center: Pasaje Rivas and Its Secrets
If there's a place that sums up underground Bogotá without needing to go down stairs, it's the Pasaje Rivas. Located between Calle 12 and Calle 12b, with an entrance on Carrera 7a and an exit on Carrera 6a, this commercial passage is an open-air tunnel, roofed with glass and metal structure, dating from 1893. It was Bogotá's first shopping center, a space where the elite went to buy imported fabrics and drink coffee while watching society pass by.
Today, Pasaje Rivas is something else. Its premises house stationery shops, bookbinding workshops, religious article sales, and, in recent years, a growing number of second-hand clothing and vinyl stores. But what few know is that beneath the tile floor lies a basement that extends under the entire block, used for decades as a warehouse and which, according to the oldest merchants, connected with the neighboring Pasaje de la Merced (currently under restoration) through a walled-up passageway.
There's no official public entrance to that basement. However, some shop owners in the central part of the passage, those who've been there for over 30 years, might let you go down if you buy something from them and they take a liking to you. The entrance is in the back room of a religious articles store that sells candles and prayer cards. I won't give you the exact name because I don't want the owner to get into trouble, but if you walk through the passage on a Tuesday mid-morning and ask for "the basement of the columns," someone will point you in the right direction.
Pasaje Hernández: The Little Brother
A block from Pasaje Rivas, on Calle 12 with Carrera 6a, is the Pasaje Hernández, built in 1905. It's shorter and less busy, but its cast iron and glass structure is an architectural gem that many overlook. Its basement, now a warehouse for a candy distributor, preserves the rails of an old pulley-operated goods transport system. If the warehouse man is in a good mood, he'll let you see the original pulleys. If not, at least you can take photos of the facade from the street, which is spectacular.
3. Cellars of Parque Nacional: Cold War Bunkers and Political Graffiti
The Parque Nacional Enrique Olaya Herrera, on Carrera 7a with Calle 36, is one of Bogotá's green lungs. Whole families go for picnics, couples to kiss on benches, and athletes to jog. But beneath the lawns, on the slopes facing Calle 34, there are a series of concrete bunkers built in the 1950s, during the Cold War, as anti-aircraft shelters for high government officials.
Official history says they were maintenance warehouses for the aqueduct. Unofficial history, backed by declassified plans that circulated on social media in 2021, says they were emergency communication centers. What is certain is that today these bunkers are the favorite canvas for the city's political graffiti artists. The interior walls are covered with murals narrating the history of the Colombian conflict, with phrases like "memory is not buried" and portraits of murdered social leaders.
Access is complicated. The main entrances are sealed with grilles and padlocks, and the National Police make frequent rounds. But there's a side entrance, on the side facing Carrera 7a with Calle 34, which sometimes opens for urban art students to maintain the murals. If you see the grille open, you can enter. If not, don't try to force it: the fine for trespassing is high, and the risk of falling through the holes in the floor, which are full of debris and glass, is real.
The Government Building Bunker
Beneath the headquarters of the Gobernación de Cundinamarca, on Plaza de Bolívar, there's another bunker, this one documented and in good condition. It was built in 1965 and served as a command center in case of a nuclear attack. It has concrete walls one meter thick, its own ventilation system, and a map room that still preserves the original boards. It's not regularly open to the public, but every November, during the commemoration of the independence cry, the Government organizes an open house for groups of up to 15 people. Entry is free, but you must register at least a month in advance at the citizen service office.
4. The Historic Sewage System: Guided Tour of 19th-Century Bogotá's Drainage
This isn't for everyone. If the smell of dampness bothers you, if you don't like enclosed spaces, or if you suffer from claustrophobia, skip this section. But if you're one of those who get excited about 19th-century engineering, keep reading: the Empresa de Acueducto y Alcantarillado de Bogotá (EAAB) has organized, since 2023, a program of technical visits to the historic sections of the city's drainage system.
The star tour is the Colector San Francisco, a brick and stone channel running beneath Avenida Jiménez, built between 1886 and 1893 to channel the San Francisco River. It's a masterpiece of the era's engineering: five-meter-high brick vaults, semicircular arches, and a slope calculated to the millimeter so water would flow by gravity. During the tour, which lasts about two hours, you walk on elevated metal walkways and see the marks of the original bricks, some with the signature of the kiln where they were made.
The tour takes place once a month, with groups of up to 20 people. You must wear rubber boots, a helmet, and a flashlight (all provided by EAAB). Registration is done through the company's website, in the "water culture" section. The cost is $25,000 COP per person, and spots sell out within hours. If you don't get a spot, there's a shorter version, one hour long, that covers a section of the Colector Arzobispo, on Calle 13 with Carrera 3a, which is less impressive but equally historic.
The Calle 26 Tunnel
Another fact for engineering enthusiasts: beneath Calle 26, at the Centro Internacional, there's a pedestrian tunnel that connected the old Techo airport (now Parque Simón Bolívar) with the city center. It was built in 1932 and used for decades to transport luggage and mail between the airport and the train station. Today it's sealed, but you can see its entrance from the south side of Calle 26, between Carreras 5a and 7a, marked with a bronze plaque reading "Túnel de Techo, 1932". The plaque is so corroded that almost no one notices it.
