A famous tango venue featured in many films. The building has beautiful architecture, and there are tango lessons and Milongas (dance parties) offered there daily.
At the turn of the twentieth century Argentina was one of the world's richest countries and this theatre was built 1989 - 1908 when Argentina was at its apogee. The owners of the theatre set out to surpass the famed European theatres by erecting an astonishingly lavish building. The building covers a whole city block and the walls are lined with European marble or at least those sections of the walls not lined with gold leaf are. The project has been a resounding success. Modern experts declare the acoustics of the theatre to be the best in the world for opera and Argentinians are so fond of the theatre they queue around the block to renew annual subscriptions. In the early twenty-first century the theatre was completely renovated. Spanish and English tours run regularly and are very popular.
Palace of Justice of the Argentine Nation
Designed by French arquitect Norbert Maillart. Built 1905-1910, it is where the Supreme Court resides.
A beautiful hidden gem in Buenos Aires. It was built in a way that buildings on one side are a 'mirror' of the ones in front of them. You'll also find 'Casa Raab', an antique clock shop, featuring a nice old watch that complements really well with the atmosphere of the street.
Don't miss this architectural gem in Buenos Aires, designed in accordance with the cosmology of the Divine Comedy. Reserve a guided tour in advance (night or day) and enjoy one of the best views of Buenos Aires. If you do not book a tour, they will not let you into the lower floor. However, try to sneak in with another tour or head in, asking for a tour. The tour counter is on the other side of the lower floor, so enough time to see the lower floor and take pictures. Palacio Barolo has just about priced itself out of the market.
