Hotel Las Naciones

Hotel Las Naciones is a 30-story high-rise in downtown Buenos Aires offering 100 rooms and 8 suites. The structure features a bronze-anodized aluminum curtain wall with dark glass windows, five underground parking levels, conference spaces on the ground floor, and guest accommodations distributed across the upper floors.

The architectural project began in 1976 under the direction of Juan Manuel Borthagaray, Mario Gastellu, and Carlos Marré, with completion in 1982. This period saw downtown Buenos Aires expanding with modernist high-rises that employed new materials and construction techniques.

The building reflects the architectural tastes of 1980s Buenos Aires through its metal and glass exterior that defines the downtown skyline. The polished stone in the lobby shows the craftsmanship valued in major construction projects of that era.

The building is accessible from street level through multiple entrances, making it easy for visitors to reach the main areas. Conference rooms located near the ground floor entrance facilitate navigation for meetings and events.

In 2012, authorities uncovered a tax evasion operation involving approximately 130 individuals operating from the hotel. This discovery highlighted how commercial buildings can become centers for organized financial fraud schemes.
