The temple to the Roman god Saturn was dedicated in the Roman Forum; its anniversary was celebrated as Saturnalia.

The Temple of Saturn was an ancient Roman temple to the god Saturn, in what is now Rome, Italy. Its ruins stand at the foot of the Capitoline Hill at the western end of the Roman Forum. The original dedication of the temple is traditionally dated to 497 BC, but ancient writers disagreed greatly about the history of this site.

Saturn was a god in ancient Roman religion, and a character in Roman mythology. He was described as a god of time, generation, dissolution, abundance, wealth, agriculture, periodic renewal and liberation. Saturn's mythological reign was depicted as a Golden Age of abundance and peace. After the Roman conquest of Greece, he was conflated with the Greek Titan Cronus. Saturn's consort was his sister Ops, with whom he fathered Jupiter, Neptune, Pluto, Juno, Ceres and Vesta.

The Roman Forum, also known by its Latin name Forum Romanum, is a rectangular forum (plaza) surrounded by the ruins of several important ancient government buildings at the centre of the city of Rome. Citizens of the ancient city referred to this space, originally a marketplace, as the Forum Magnum, or simply the Forum.

Saturnalia is an ancient Roman festival and holiday in honour of the god Saturn, held on 17 December in the Julian calendar and later expanded with festivities until 19 December. By the 1st century BC, the celebration had been extended until 23 December, for a total of seven days of festivities. The holiday was celebrated with a sacrifice at the Temple of Saturn, in the Roman Forum, and a public banquet, followed by private gift-giving, continual partying, and a carnival atmosphere that overturned Roman social norms: gambling was permitted, and masters provided table service for their slaves as it was seen as a time of liberty for both slaves and freedmen alike. A common custom was the election of a "King of the Saturnalia", who gave orders to people, which were followed and presided over the merrymaking. The gifts exchanged were usually gag gifts or small figurines made of wax or pottery known as sigillaria. The poet Catullus called it "the best of days".
