Themed tours in Buenos Aires offer an in-depth look at these secrets.
These excursions depart from the classic tour to focus on specific narratives: from Freemasonry in the old town and the exploration of Jesuit tunnels, to visiting closed-door bars inspired by local legends.
In this article, you'll find the best tours and excursions near Buenos Aires , as well as urban circuits that reveal the city's hidden side. We'll explore options for a nighttime tour of mysterious Buenos Aires, uncover the hidden stories of prominent figures from the city, and revisit the settings of its most famous urban legends.
A circuit of tunnels, crimes and urban legends
The history of Buenos Aires is marked by epidemics, underground defensive structures, and tragedies that gave rise to numerous popular legends. The best way to explore these stories is to wander through the southern neighborhoods and the historic center, where period architecture serves as the main backdrop.
Let's see what stories are hidden in these streets.
Mysterious Buenos Aires Tour: Saint Felicitas and Freemasonry
One of the more unusual tours is the Mysterious Buenos Aires tour , which focuses on the dark tales of the historic center and the southern part of the city . The itinerary includes stops at emblematic sites such as the Santa Felicitas Museum , located at 1480 Pinzón Street in the Barracas neighborhood.
This church was built by the Guerrero family in memory of Felicitas, a young widow murdered in 1872 by a rejected suitor. Urban legend says that her figure, dressed in white, wanders through the church every January 30th .
Beyond the myth, the site retains its heritage value. Currently, guided daytime tours are offered between 3:00 and 5:00 PM, covering the Tunnel Museum and the Hidden Temple. Another option for nighttime tours is "History Fiction," which combines historical narrative with theatrical performances and a tasting of period liquors .
Another essential stop for exploring the mysteries of Buenos Aires on a tour is the Barolo Palace, at Avenida de Mayo 1370. This building, inaugurated in 1923, was designed according to strict mathematical proportions and Masonic references, emulating the structure of Dante Alighieri's "Divine Comedy." After exploring the hidden symbolism in its vaults, the visit culminates at the lighthouse located in the dome, 100 meters high.
Colonial tunnels in the Church of San Ignacio de Loyola
The Church of San Ignacio de Loyola houses a network of 18th-century Jesuit tunnels in the Monserrat neighborhood , at 225 Bolívar Street. Although historians agree that their construction served defensive and logistical purposes to connect the order's buildings, there are no official written records from the Spanish crown documenting their exact use.
Guided tours allow visitors to explore a restored 35-meter underground section. The tour concludes with a climb to the upper levels and the south tower of the temple . From there, a panoramic view of the historic center unfolds, creating a visual map between the colonial grid and the modern city.
Zanjón de Granados: I discovered the underground tunnels of San Telmo
Today, the Zanjón de Granados functions as an archaeological museum. Its restoration took 38 years to recover living fragments of the capital's urban and social evolution. Original quebracho wood roofs, adobe floors, cisterns, and water tanks lined with French tiles were repaired. The latter stored rainwater, and, remarkably, families used to raise sea turtles inside them to purify it.
This historic passageway is located at the corner of Defensa and San Lorenzo streets, in the heart of San Telmo. Hidden within it is one of Buenos Aires' oldest underground systems. It is believed that its tunnels once connected Plaza de Mayo and other key locations in the city via underground passages.
The discovery of these tunnels in San Telmo began in 1985 when the buyer of the abandoned property started his project to open a restaurant. Under layers of rubble and garbage were the remains of a house dating back to 1830. Further down, the storm drain system was revealed.
The investigation of the ruins revealed that the house belonged to the Miguens family , of Spanish origin. It had 23 rooms, a kitchen, two bathrooms, and three courtyards: one for reception, another for the family, and a third for the servants.
Beneath the mansion, 18th-century arches were found, suggesting a previous structure existed. The discovery of tunnels over three meters high , with brick walls weathered by water, indicated that the storm drains had been built by the residents themselves to control flooding.
According to urban planning research, the house was abandoned around 1860 , possibly due to the yellow fever epidemic. After the epidemic, the streams were channeled underground, and in 1892, with the installation of running water, the tunnels became obsolete. Some residents used them as basements, while others filled them in.
At the beginning of the 20th century, the building was adapted for new uses. Shops operated on the ground floor, while the first floor became a tenement that housed about thirty immigrant families.
