The mission also serves as a museum, preserving its own history and the history of the area. There are four specific museum galleries: the Harry Downie Museum, describing restoration efforts; the Munras Family Heritage Museum, describing the history of one of the most important area families; the Jo Mora Chapel Gallery, hosting a cenotaph sculpted by Jo Mora as well as rotating art exhibits; and the Convento Museum, which holds the cell Serra lived and died in, as well as interpretive exhibits.
