Pantheon Rome Discover the Ancient Dome, Oculus and Timeless Roman Architecture

Pantheon Rome Complete Visitor Guide 2026

Located in Rome’s historic center, the Pantheon is among the best-preserved monumental buildings of the ancient Roman world. The surviving structure largely dates to the reign of Emperor Hadrian in the second century CE, although an earlier building on the site was associated with Marcus Agrippa.

Its most celebrated feature is an immense unreinforced concrete dome with a circular opening called the oculus.

The building became a Christian church in 609 CE, helping preserve its remarkable architecture.
