The hidden treasures of Plaza Constitución, Buenos Aires’ palace-like station

On a busy weekday morning, a group gathers beneath the bust of General Julio Argentino Roca in the central hall of Buenos Aires’ Plaza Constitución station. They are not passengers checking platforms. They are visitors joining one of the station’s regular free guided tours.

The terminal, once the main station of the Ferrocarril del Sud, is among the largest in the world by passenger traffic and architectural significance. The tour explores areas normally closed to the public and draws attention to the building’s history, design and restored ornamentation.

Plaza Constitución opened in 1864 and was declared a National Historic Monument in May 2021. Its 14 platforms handle about 700,000 people each day, making it Argentina’s busiest railway terminal. When it opened, the surrounding street was unpaved, and the station primarily served freight rather than passengers.

The bust of Roca was installed in 1948, when President Juan Domingo Perón’s nationalization of the railway system changed the Ferrocarril del Sud’s name to General Roca. The guide explains that the monument was placed to honor the new name.

The central hall reflects the terminal’s aristocratic origins and French architectural inspiration. Restored marble, lighting and decorative details give the building a palace-like atmosphere that many commuters pass without noticing. The tours invite visitors to look upward, enter restricted sections and see the station as more than a place to catch a train.

That year, the Ferrocarril del Sud became General Roca, which is why the bust was installed in his honor.
