The Pantheon in Rome is one of the most famous buildings from the ancient world still in continuous use as a place of worship. Few people who visit today realize that it is neither the original Agrippan Pantheon, as the famous inscription on the portico claims, nor that its interior was substantially altered from the renaissance to the eighteenth century.

The Pantheon as we see it today is a dramatic rebuilding of the original Augustan era building by the emperor Hadrian sometime around 125 AD. Most of the original exterior stone and bronze ornament from the exterior were stripped from the building beginning in the late middle ages. Two bell towers were added to the roof which were subsequently removed, and in 1747 the interior attic was altered to ‘correct’ the ancient design. In the twentieth century a small portion of the original Hadrianic attic was restored based on paintings made prior to the modern changes.

RWC Atelier & Co has made a series of drawings proposing a number of rebuilding ideas which are depicted here on the website, along with links to reconstruction images and models of the ancient building in antiquity.
