Pantheon

Pantheon or Pantheon, at Rome, a magnificent temple consecrated, as the name implies, to all the gods, built by Hadrian (emperor AD 117–38) to replace that of M. Agrippa built 27–25 BC in the Campus Martius. It consists of a huge domed rotunda with a pedimented portico, and the basic structure (although not the decoration) has survived virtually intact. It was dedicated as a Christian church by Pope Boniface IV in AD 609.
