It is an art gallery that has 2 locations in Guimarães: da Rainha street and Gravador Molarinho street. It's dedicated to modern and contemporary art and has temporary exhibitions of paintings and sculpture by Portuguese artists. They also sell artworks. Last year, during my short stay in the city, the sculptural works of Portuguese artist Susana Piteira (susanapiteira.Com) were being shown. The gallery is open Tuesday to Saturday from 10.30 to 13 and from 15.30 to 19.00.
