What to see inside Milan Duomo
Inside Milan Duomo the plan is a cross with five aisles. Construction started at the apse, the east end, and then moved to the transept and the bays of the nave. The cathedral is still an active church, so the visitor route passes services, prayer areas and roped-off sections. Prayer and Mass are free and use their own entrance, but they are no substitute for a visitor ticket.
The standard visit covers the cathedral, the museum and San Gottardo. Extras such as the crypt and the archaeological area are priced separately. For all options, see the Duomo tickets page.
The nave, the floor and the altars
The big space comes first.
The tall piers of the nave divide the church into five aisles, and the inside is large: the interior covers about 11,700 square meters. Do not confuse the inside figures with the outside dimensions of the whole building.
The cathedral was not finished in one style. In the centuries after the Gothic start, the Borromeo archbishops reworked the presbytery, altars, crypt and floor. So you see a Gothic shell with later fittings, not a single-period interior. Tombs and side altars line the aisles, and the details reward a slow walk.
Our pick: the cathedral interior

The stained glass windows
Clearest in daylight, in the apse and along the aisles.
The cathedral has 55 stained glass windows with more than 3,600 figures. They mix older and newer glazing, so do not assume that every window is a medieval original. Bomb damage in 1943 hit the apse windows among other parts, and the postwar years brought replacements and restoration.
The museum shows historic glass up close, which is useful if the windows in the church are hard to read from the floor. See the Duomo Museum page for that part of the visit.
Saint Bartholomew and the meridian
Two details that many visitors look for.
San Bartolomeo by Marco d'Agrate
The statue dates from about 1562 and shows the apostle with his skin removed. It was restored and has stood in the retrochoir since 2025.
The meridian line
A brass line runs through the floor near the entrance, south to north. Light enters through an opening about 24 meters up. It was commissioned from astronomers of the Brera observatory in connection with the time reform of 1786.
The treasury
The cathedral treasure is not a free-standing treasury in the church route. The museum tour begins with it, followed by sculptures, glass, paintings, tapestries and models.
Museum guide →The crypt, the archaeological area and what they cost
These need an extra ticket on top of the cathedral.
| Area | Price 2026 | Hours | What to know |
|---|---|---|---|
| Archaeological area under the square | €5 extra | 9:00 to 19:00, last entry 18:00 | A valid cathedral ticket is also needed |
| Scurolo di San Carlo | €3.50 extra | Mon to Fri 10:00 to 17:00, Sat 10:00 to 16:00 | Sunday hours vary, so go on a weekday |
Under the square lie remains of the early churches of Santa Tecla and San Giovanni alle Fonti. The baptistery was built in 378, and Ambrose baptized Augustine there in 387. You see an eight-sided room with an octagonal font, and parts of the apse of Santa Tecla. The Scurolo is a separate chapel and should not be mixed up with services held in the crypt.
The baptistery of Santo Stefano is a different site. It is open by free group request only: ask at least 5 working days ahead, for up to 10 visitors plus a guide. Do not plan on walking in as an individual.
