Pantheon - Basilica di Sancta Maria ad Martyres
- Piazza della Rotonda
Dedicated to all the gods by general Marcus Vipsanius Agrippa, who commissioned it to celebrate Augustus’s victory over the Persians, it was later rebuilt by Emperor Hadrian. It is almost a perfect sphere, 43 metres in diameter and vaunting a concrete dome with an oculus. In addition to Raphael, Annibale Carracci, Perin del Vaga, Margherita di Savoia and kings Umberto I and Vittorio Emanuele II are all buried here.
