The Pantheon

Piazza della Rotunda

The Pantheon still holds the record as the World's largest unreinforced dome.
Named from Latin meaning 'every god' it was first commissioned by Marcus Agrippa as a temple to all the ancient Roman gods and reconstructed by Emperor Hadrian around 126 AD into a circular building with an occulus in the dome's ceiling.
During the 7th century the Pantheon was consecrated as a Roman Catholic church and has been used during Renaissance times as a burial tomb for Raphael and Annibale Carracci.
Later two Italian Kings, Vittoria Emanuele II and Umberto I were buried here.
