Doors of the Pantheon

“The oldest doors still in use in Rome. Cast in bronze for emperor Hadrian’s rebuilding, they date from about 115 AD.

Each door is solid bronze seven and a half feet wide & twenty-five feet high, yet so well balanced they can be pushed or pulled open easily by one person.

Becky for scale.”
