Pantheon
Walk in, look up, and you have basically got it. The Pantheon is the best-preserved building left from ancient Rome, standing nearly intact after almost two thousand years. It started as a temple to all the gods and has been a working church since the 600s, which is part of why it survived. The concrete dome and the open oculus at the top still draw architects.

Go, and it barely costs you any time. The best-preserved monument of ancient Rome, and the open oculus is worth the short stop even with the new small entry fee. To skip paying, go on the first Sunday of the month when entry is free, if you do not mind queueing for a walk-up ticket.
Worth it for
- Standing under the coffered dome with the open oculus overhead
- History and architecture fans, since the building is remarkably intact
- A tight schedule, since it is a quick, central stop that still delivers
You can skip if
- You expected a long visit, since it is essentially one grand room
- You turn up at a peak hour with no reserved slot and the line is long
Tickets & tours for Pantheon
Which ticket should you buy?
An ancient building that never closed
The Pantheon you see was built under the emperor Hadrian around 125 AD, replacing an earlier temple put up by Agrippa, whose name still runs in large letters across the front. The inscription says Agrippa built it, but the current structure is Hadrian's reconstruction.
In the early 600s the building was given to the Church and consecrated as a Christian place of worship. That continuous use is the main reason it avoided the quarrying and ruin that befell most ancient Roman monuments. It has functioned as a church ever since, and still holds Mass.
The dome and the oculus
The interior is a perfect sphere geometry: the height to the top of the dome equals its diameter, so a ball of the dome's width would just touch the floor. The coffered concrete dome was the largest of its kind for centuries and remains the world's largest unreinforced concrete dome.
At its center is the oculus, a round opening about nine meters wide that is open to the sky. It is the only natural light source, and a shaft of sun tracks across the interior through the day. Rain does come in, and the sloped marble floor has drains to carry it away. Looking straight up through the oculus is the building's signature moment.
What is inside
Beyond the architecture, the Pantheon is a burial place. The Renaissance painter Raphael is entombed here, his grave marked and usually marked out for visitors. Two kings of unified Italy, Vittorio Emanuele II and Umberto I, are also buried inside, and their tombs are tended by volunteer guards.
Because it is an active church, the space is treated as a place of worship as well as a monument. There are side chapels and altars in use, and staff may ask for quiet and appropriate dress. Services can affect access at certain times.
Visiting and tickets
For most of its modern life the Pantheon was free to enter, but a paid timed-entry ticket was introduced in 2023. On regular days you now book a ticket for a one-hour slot, with reduced rates for younger visitors and free entry for children. Tickets can sell out a few days ahead on weekends and holidays, so booking online saves waiting.
There are still free days: entry is free on the first Sunday of each month, when you cannot reserve online and instead queue for a ticket at the door. The building is closed on a few major holidays through the year. It sits on Piazza della Rotonda in the historic center, an easy walk from the Trevi Fountain and Piazza Navona.
