Why go
The Pantheon is unusually complete, allowing the portico, rotunda and dome to be read as one composition rather than reconstructed from ruins. Its equal interior height and diameter create a perfect sphere in principle, while the open oculus changes the light—and admits rain—throughout the day.
What to look for
- Stand beneath the oculus and follow the five rings of coffers as they lighten the dome toward its center.
- Compare Agrippa’s inscription on the portico with the Hadrianic building behind it.
- Look for the subtle drainage holes in the slightly convex floor beneath the open sky.
Useful to know
- Allow 45–60 minutes and pause long enough for your eyes to adjust to the single overhead light source.
- Religious services can alter visitor access, so check the current official timetable before setting out.
- Santa Maria sopra Minerva is one block away and provides a useful Gothic contrast.
