Veneranda Fabbrica del Duomo · Piazza del Duomo, pin set by option
This is the cathedral guiding itself: the Veneranda Fabbrica's guides, a separate fast-track entrance, the nave, the terraces by lift and the archaeological area with the Baptistery of San Giovanni alle Fonti, in Italian, English, Spanish, German or French. Pick it for the baptistery and the official guides, and book it with care, because the listing states it is non-refundable.

Of the eight listings on this site, this is the one where the guide works for the building. The Veneranda Fabbrica has run the cathedral since 1387 and its own guides lead this tour: about an hour and a half with a headset, starting through a separate fast-track entrance, through the nave, up to the terraces by lift, and then down under the parvis to the archaeological area, where the fourth-century octagonal basin of the Baptistery of San Giovanni alle Fonti is where tradition says Ambrose baptised Augustine. The other listings on this site do not mention it.
At the end you keep a pass for the Duomo Museum and the Church of San Gottardo in Corte, to use on your own afterwards. Both are closed on Wednesdays. The listing offers a shared small group or a private tour, in Italian, English, Spanish, German or French, though the shared and private versions do not always offer the same languages on the same day, and it notes that if the terraces are closed by weather the guided tour visits the museum instead. The lift goes up to the terraces; the listing warns that the staircase to the highest terrace is narrow, and it rules the tour out for wheelchair users and people with mobility impairments.
Two things to settle before booking. The meeting point is a map pin that changes with the option you choose, and the group and private pins differ, so read the voucher rather than heading for the facade. And the listing states the booking is non-refundable, which is unusual for a guided tour; the operator tours on this site cancel free up to 24 hours before. Bring a passport or ID card and comfortable shoes.
The meeting point is set by the option you booked; group and private tours use different pins on Piazza del Duomo. Open the voucher's map the night before and allow ten minutes to cross the piazza.
Headsets on, then in through the Fabbrica's fast-track entrance. The security check still happens, but you are not in the main ticket queue.
The guide covers the Candoglia marble, the Gothic structure, the glass and the works of art inside, with the detail you get from an institution that is still finishing the building.
Up by the lift, then the narrow staircase to the highest terrace for those who want it. Spires, buttresses and the Madonnina on the main spire, 108.5 metres above the piazza. If the roof is shut by weather, the listing swaps in the museum.
Down to the archaeological area: the remains of the Baptistery of San Giovanni alle Fonti, the octagonal font of the fourth century, and what else lies under the parvis. There are about 27 steps down.
The guided part ends. Your pass covers the Duomo Museum at Piazza del Duomo 12 and San Gottardo in Corte, open from 10:00 and closed on Wednesdays. The two-hour version of the tour extends the guided time on the terraces.
Ticket included more than we realised at the time of booking.
