The surprise of the Pantheon lies at the threshold. A columned portico gives way to a circular room, and the dome gathers the whole interior beneath a single opening to the sky. Take in the floor and the wall chapels before looking up: the building’s coherence comes from their relationship.
Agrippa’s name, Hadrian’s building
Follow the light, then the floor
A monument and a place of worship
The basilica remains a place of worship. Dress and behave accordingly, and check the official visitor page for ticket arrangements and access around religious celebrations. A sightseeing visit and attendance for worship follow different arrangements.1
