Temple of Cybele

The Temple of Cybele or Temple of Magna Mater was Rome's first and most important temple to the Magna Mater, who was known to the Greeks as Cybele. It was built to house a particular image or form of the goddess, a meteoric stone brought from Greek Asia Minor to Rome in 204 BC at the behest of an oracle and temporarily housed in the goddess of Victory's Palatine temple. The new temple was dedicated on 11 April 191 BC, and Magna Mater's first Megalesia festival was held on the temple's proscenium.

The temple was sited on the high western slope of the Palatine, overlooking the valley of the Circus Maximus and facing the temple of Ceres on the slopes of the Aventine. It was accessible via a long upward flight of steps from the flattened area or proscenium below, where the goddess's festival games and plays were staged.
