Seyhoun Art Gallery was founded in 1966 in Tehran by the painter Massoumeh Noushin Seyhoun. It is described as the most long-lived art gallery in Iran and has presented many of the leading figures of contemporary Iranian art. The gallery has held more than 1200 exhibitions of painting, sculpture, photography and graphic art. It has also shown international trends such as installation, conceptual, video and digital art, and it continued its activities through the unrest around the 1979 revolution. Beyond exhibiting, it has helped shape Iranian modern art, held official art fairs, supported artistic relations between Iran and Western countries, and offered expertise and pricing services for classical and modern Iranian art. It aims to identify and introduce new talents whose work meets international principles while keeping an Iranian identity.
