This is not really an art gallery - though there is a gallery. This is an art school, one of the many in town - housed in an incredibly lovely old building. There is also a cafe that makes good coffee though better baked goods can be had across the street at La Buena Vida.
The building used to be part of the convent next door (Las Monjas) but the stairways are the only original bit left of the interior - or so I was told.
As you enter, the exhibition gallery is to the left after the second entry archway. While I was there the exhibit was of some pieces made of slick plastic sheeting stabbed through with long plastic things - the thingies that stores use to attach price tags to clothes. I would say the exhibit was definitely odd - especially the piece shaped like a hairy teepee.
Anyway, the courtyard is a great place to waste time, it's shady and has a lovely fountain.
In the far northwest corner is a room that is unlocked only a few hours a day. It contains an unfinished mural of the life of Allende by David Alfaro Siqueiros. The legend of the mural is that the school, which was once private, went bankrupt and couldn't afford to pay for the mural to be finished. However, my tour guide told me that the legend is wrong - that she knew some of his students and that the mural was finished by the artist and then was painted over as a lesson for his students to do it over again with him - but he got into a fight with the school's administration and left. I suppose the room could be x-rayed to discover the truth but in the meantime a controversy, no matter how small, is always a good thing.
There are other murals around the building,not many but they are good ones, all painted in the 1940s.
At night there are films, art exhibits, musical events, etc. at the Bellas Artes. A schedule is always on the chalk board at right inside the front door.
