Climbing the dome is part architecture tour, part cardio. It’s thrilling and intimate — you enter the cathedral’s anatomy, brushing past stone and brick.

The Path
- Timed entry; arrive 10–15 minutes early.
- Narrow staircases; occasional passing bays.
- Fresco gallery: pause respectfully; enjoy proximity without touching.
- Terrace: linger; the city spreads out like a painted map.
What You’ll See Up Close
- Last Judgment frescoes — angels, trumpets, and figures by Vasari and Zuccari.
- Brickwork clues — glimpses of the herringbone pattern.
- Mechanics — stair geometry inside the dome’s thickness.

Tip: Travel light; backpacks scrape walls and slow ascents.
Safety and Comfort
- Hydrate before the climb.
- Claustrophobia? Consider the Campanile instead.

What to Bring

Photo Angles

- Terrace panoramas: overlap frames for later stitching.
