The Chácara do Céu Museum and the Açude Museum constitute the Castro Maya Museums. They were residences of the collector and patron of the arts Raymundo Ottoni de Castro Maya, who donated the real estate and the entire collection to the Foundation that bore his name. The Foundation was closed in 1983, when the museum was incorporated into the Brazilian government, and today it is part of the Instituto Brasileiro de Museus, connected to the Ministry of Culture.
