Buenos Aires City Hall

Buenos Aires City Hall is a municipal government palace with Beaux-Arts architecture located across from Casa Rosada on Plaza de Mayo. It features carefully worked stonework and symmetrical proportions that define its classical appearance.

Construction began in 1890 under Mayor Francisco Bollini and marks the start of a phase of major urban modernization. An annex was later added to accommodate the administrative needs of the growing city.

The building embodies Argentine institutional design and shows how Buenos Aires developed into a modern metropolis during its period of rapid transformation. Its detailed exterior reflects the confidence and ambition of a city that was reshaping itself.

The building sits directly on Plaza de Mayo and is easy to spot from the street, especially if you visit Casa Rosada nearby. The interior remains in administrative use during weekdays, but you can view the exterior and surroundings at any time.

A time capsule was placed inside the cornerstone on New Year's Eve 1890 and holds objects from that era. This hidden memory documents what the city considered important at the beginning of its modern age.
