Why visit
The best-preserved building of ancient Rome, still standing after 1,900 years, with the largest unreinforced concrete dome in the world. The oculus opens straight to the sky — light moves through the room like a clock.
History
Rebuilt by Hadrian around 126 AD on the site of an earlier temple by Agrippa. Continuously in use for nearly 1900 years.
What to see
The 9-metre oculus, Raphael's tomb, the kings of Italy and the perfect proportions of the dome.
Anu's local tip
If it starts raining while you're inside, stay. The oculus becomes a live water column — one of the most beautiful moments in Rome.
Photo spot
Stand under the oculus and shoot straight up. Outside, the columns from the corner of Piazza della Rotonda at dusk.
Common mistake to avoid
Skipping the small entry fee reservation online. Free entry days exist but lines wrap the square — pre-book the timed slot.
Nearby
Piazza Navona (4 min walk), Sant'Eustachio for the best espresso, Giolitti for gelato.
Practical tips
Tourist visits require a ticket; booking through the official channel is recommended. Admission conditions may change, so check the official site before visiting. Magical when rain falls through the oculus.
Frequently asked questions
Do I need a ticket for the Pantheon?▾
Yes, a small entry fee was introduced for tourists. Residents and worshippers attending mass enter free. Booking online avoids the queue.
What happens when it rains?▾
Water falls straight through the oculus and drains through tiny holes in the slightly sloped marble floor — exactly as the Romans designed it almost 2,000 years ago.
