The House Museum "Boschi-Di Stefano" presents an extraordinary collection of 20th-century Italian art donated to the city of Milan in 1974 by Antonio Boschi and Marieda Di Stefano, who embellished their apartment on Via Giorgio Jan all through their married life with innumerable masterpieces of painting, sculpture and drawing from period between the 1900s and the 1960s. Located in a building of the 1930s designed by Piero Portaluppi, the apartment was inaugurated as a museum in 2003 after renovation of the premises undertaken by the City Council and refurbishment for display purposes by the Boschi-Di Stefano Foundation. The rooms of the apartment thus became the ideal space to exhibit a selection of the over 200 works in the collection. Part of the collection has been on show at the Museo del Novecento since December 2010 in order to highlight the key role of private collectors in the creation of municipal collections.
