It is the world's largest unreinforced concrete dome, which means that it is mounted and supported by its own weight, without the need for additional structures.

Frequently asked questions about the Rome Pantheon dome

Why was the Rome Pantheon dome built?

Emperor Hadrian likely envisioned the dome to connect mortals to the heavens. Through the shaft of light that pools in through the oculus, the dome acted as a celestial mode of communication. He wanted to give the Romans an architectural masterpiece they could be proud of, and hence the Pantheon itself was reconstructed during his reign.

At what time of the day should I see the Pantheon Dome to fully appreciate its beauty?

Visiting the Pantheon in the soft hours of the morning, or between 11 and 1 pm offers a great chance to view it in all its splendor. As the sun pools in through the oculus, the dome is lit up, bathing it an almost golden glow. When it's cloudy, however, the Pantheon adopts a sleepy feel, and the details of the dome may not be as distinct.

Do I need separate tickets to see the Rome Pantheon dome?

No, your entry ticket includes the dome, so you don't need to purchase separate tickets to see it.

What's the history behind the Pantheon Dome?

The Rome Pantheon's history is nothing short of fascinating. Originally constructed as a temple in 27 BC, it was rebuilt by Emperor Hadrian in 126 AD. Over the centuries, it transitioned from a pagan temple to a Christian church and has since stood as an iconic symbol of Rome's history.

Can I climb the Pantheon Dome?

No, the Dome is not located on a separate level or floor of the Pantheon. It cannot be accessed by a staircase or elevator. You can simply gaze up at its awe-inspiring dimensions once you're inside the rotunda of the Pantheon.

What's unique about the Pantheon Dome's architecture?

The dome's groundbreaking design features an oculus, a circular opening at the top, creating a harmonious interplay of light and space. It's also renowned for being the world's largest unreinforced concrete dome. The dome's construction is such that it is heaviest at the bottom and lighter towards the top, so the dome doesn't push itself outward or collapse entirely.

What are the architectural features that surround the Roman Pantheon Dome?

The dome is accentuated by the box-like coffers that encircle it. Additionally, the top of the dome opens out through the oculus. Below, the niches, altars, art work and marble floor complements the dome's magnificence. Inside the Pantheon, you'll experience the breathtaking dome, the intricate marble floor, historical artworks, and the ethereal atmosphere that bridges centuries.

Is the Pantheon Dome visible to wheelchair users?

Yes, since the dome needn't be climbed, it can easily be witnessed by wheelchair users.

Are there any events or special days to visit?

April 21 holds special significance as it is the founding day of Rome. At exactly 12pm, sunlight that pools in from the oculus lights up the Pantheon's doorway. Additionally, on the day of the Pentecost, rose petals are showered on the waiting crowds from the oculus of the dome.

Can I take photos of the Pantheon Dome?

Photography is allowed, but remember to be respectful of the sacred space and other visitors. Avoid using flash and tripods.
