Its only one floor so there isnt much to see. I think its all brazilian artists from mostly 18-19th century. It is free so if you are in the area, like art and have 30 mins-1 hr to spare worth a stop in. One strange thing we noticed was that a lot of the tourists like to have their picture taken in front of every painting, but dont actually look at it. This became slightly annoying after a whle as you are always stopping for someone to take a picture.
