The Theatre of Pompey (Latin: Theatrum Pompeium, Italian: Teatro di Pompeo) was a structure in Ancient Rome built during the later part of the Roman Republic. It was constructed in seven years from 55 BC, and was dedicated early in 52 BC before the structure was fully completed. The theatre was one of the first permanent (non-wooden) theatres in Rome. The building itself was a part of a multi-use complex that included a large quadriporticus directly behind the Scaenae frons. Inclosed by the large columned porticos was an expansive garden complex of fountains and statues. Along the stretch of covered arcade were rooms dedicated to the exposition of art and other works collected by Pompey Magnus during his campaigns.
On the opposite end of the garden complex was a curia for political meetings. The senate would often use this building along with a number of temples and halls that satisfied the requirements for them to formally meet. This is infamous as the place of Julius Caesar's murder by the Liberatores of the Roman Senate and elite.
