Temple of the Twins

Rome honors its divine horsemen

In the heart of ancient Rome, the Temple of Castor and Pollux was dedicated in the Roman Forum, honoring the divine twin sons of Zeus who were believed to have intervened at the Battle of Lake Regillus. The temple became one of the Forum's most prominent landmarks, its three surviving columns still standing today as silent witnesses to a civilization's faith in celestial protectors.
