The medieval complex was probably made up of a farm with outbuildings and an oratory, which supported the Olivetan Leper Hospital of the Santa Maria Incoronata di Nerviano Monastery. The church as it stands today is the result of refurbishment during the eighteenth century, which is in keeping with the conventional Milanese oratories of the time.
The sanctuary opens onto a square hall and has a sacristy to its right and a small atrium to its left. The facade is simple: two lesenes and the traditional exterior are topped by architraves that are the only prominent elements. An altarpiece made of tile and wood, depicting the Virgin with Child and Saints Francis of Assisi and Andrew sits above the altar.
