In the heart of Buenos Aires, facing Plaza San Martín, you will find the emblematic Paz Palace: one of the city's greatest architectural gems.

Built in the early 20th century by order of José C. Paz, founder of the newspaper La Prensa and Argentine ambassador to Paris from 1885 to 1893, it is the largest private residence in the country and one of the few residences in Buenos Aires to bear the title of Palace, given this designation due to the design and layout of its interior rooms. It was designed as a family home, with four floors, 140 rooms, and a total covered area of 12,000 m2.

A reflection of Beaux-Arts architecture, its architect was the prestigious Frenchman Louis-Marie Henri Sortais, and the construction was supervised by the prestigious Argentine architect and engineer Carlos Agote.

After being briefly inhabited by the Paz family, in 1938 it became the headquarters of the Military Circle, the National Military Library, and the National Weapons Museum.
