The Temple of Hercules Victor or Hercules Olivarius is a Roman temple in Piazza Bocca della Verità in the area of the Forum Boarium near the Tiber in Rome. It is a tholos, a round temple of Greek ‘peripteral’ design completely surrounded by a colonnade.
Dating from the later 2nd century BC, and perhaps erected by L. Mummius Achaicus, conqueror of the Achaeans and destroyer of Corinth, the temple is 14.8 m in diameter and consists of a circular cella within a concentric ring of twenty Corinthian columns 10.66 m tall, resting on a tuff foundation. These elements supported an architrave and roof, which have disappeared.
