Which South American capital city is Palacio Paz located in?

Palacio Paz, in the heart of Buenos Aires, once belonged to a wealthy family whose last name was Paz.

Once the private residence of José C Paz – founder of the newspaper La Prensa – this opulent, French-style palace (1909) is the city's grandest. Inside are ornate rooms with marble walls, salons gilded in real gold and halls boasting beautiful wood-tiled floors. The pièce de résistance is the circular grand hall with mosaic floors, marble details and a stained-glass cupola. Nearly all materials came from Europe and were then assembled here.

The National Museum of Armaments (Spanish: 'Museo de Armas de la Nación') is also housed in the Paz Palace. Argentina's most important military museum, it was inaugurated in 1941 and includes 15 rooms where its collection is divided chronologically and by country of origin. Its oldest pieces include a chain mail armor belonging to the Byzantine Emperor Comnenus (c. 1100), crossbows, maces, two-handed swords, flails and other weapons dating from the Crusades, and an arquebuse used during the Battle of Aguere in Spain.
