The Duomo Museum, or Museo del Duomo, is devoted to Milan Cathedral and its extraordinary history. Set in the Palazzo Reale on the south side of Piazza del Duomo, it brings together sculpture, stained glass, tapestries, paintings and treasures made for the great Gothic church next door.
Construction of the cathedral began in 1386 and continued for centuries, shaped by Milanese craftsmanship, civic ambition and the patronage of the Visconti and Sforza families. The museum tells that story through carved figures, architectural fragments and a large wooden model used to guide the cathedral’s design. Many sculptures are originals removed from the building for conservation or replaced by copies.
The stained-glass panels are especially rewarding: here you can see their colour and detail at eye level rather than from the cathedral floor. A visit also gives the rooftop spires and statues more context, turning the facade’s dense decoration into a collection of individual works with stories of their own.
Allow around 90 minutes, and consider visiting before the cathedral to get more from what you see there. Check current opening days and compare ticket options in advance, as some combined Duomo passes include the museum. Duomo station, served by metro lines M1 and M3, is a short walk away.
