The Temple of Castor and Pollux is at one end of the Roman forum, near the Arch of Septimius Severus. During the battle of Lake Regillus against the Etruscans, in 496 BC, some people said they had seen the twin gods Castor and Pollux helping the Roman side.
After the Romans won the battle, they decided to build a temple to honor the gods who had helped them. That temple was finished in 494 BC, in the early Republic, and when it got old it was rebuilt in 117 BC, and restored again in 73 BC.
In 14 BC or 9 BC, a fire necessitated significant rebuilding in the Forum. Augustus took the opportunity to rebuild the Temple of Castor and Pollux while also connecting it to the imperial cult. The original temple had burned down, and Tiberius built a new one in 6 AD. So the Corinthian-style temple you see today is from the Julio-Claudian period. This temple was used to keep some of the imperial treasury in it.
