Palacio de Bellas Artes, Mexico City
If asked what the most beautiful building in Mexico is, the Palacio Bellas Artes - next to Alameda Park - would probably win hands down. This neo-classical building, built around 1900, is a cultural center which hosts concerts and theater shows as well as temporary exhibitions. The interior is held in Art Nouveau and Art Deco-style and contains famous "murales" frescoes. Note:
In January 2014 extensive renovation works were going on and the murales were not accessible. This should change in a few months.
Not too far from the Zocalo, is the Palacio de Bellas Artes, arguably the most beautiful building in the Historic Center. The exterior of the building is clad in Italian marble and its cupolas are covered in tiles. The walls of the second and third floors are covered in murals by Rufino Tamayo, David Alfaro Siqueiros and Jose Clemente Orozco.
The beautiful Museum of Fine Art is located right next to the Alameda Park. The building of the place started in 1904, on the remains of an old convent. The ground in Mexico City is very unstable because much of it is built over a lake, and they had big problems when the buildingprocess started. A lot of the buildings in the city are sinking, but this may be the place where you best can see it. When it was constructed it was on the same level as the street, but it weighs a lot of tons and today it is a few meters lower.
While they were building the palace the revolution broke out, and it delayed the process even more. Finally in 1934 it was finished. Because of this you can see that the building is more neo-classical and art nouveau on the outside, while the inside looks much more like art deco.
There are some beautiful murals here by Rivera, Siqueiros, Orozco, Tamayo and Montenegro. They also have the glass Tiffany curtain which is made of almost a million individual pieces! On this the modern mexican landscapepainter, Doctor Atl, have depicted the volcanoes of Mexico.
When I was there they also had a large exhibition about Frida Kahlo, but I think it was just temporarily.
