Pantheon

This guide to the Pantheon in Rome traces the building across fourteen centuries, from Emperor Hadrian's second-century reconstruction and his decision to inscribe another man's name over the door, to the tomb of Raphael, buried here in 1520 beside a fiancee he spent six years declining to marry. It follows the oculus overhead and the disc of light it has cast across the marble floor since antiquity. Stand near the center of the floor to watch that light make its slow crossing.
