The Teatro Olimpico ("Olympic Theatre") is a theatre in Vicenza, northern Italy, constructed in 1580-1585. The theatre was the final design by the Italian Renaissance architect Andrea Palladio and was not completed until after his death. The trompe-l'œil onstage scenery, designed by Vincenzo Scamozzi, to give the appearance of long streets receding to a distant horizon, was installed in 1585 for the very first performance held in the theatre, and is the oldest surviving stage set still in existence. The full Roman-style scaenae frons back screen across the stage is made from wood and stucco imitating marble. It was the home of the Accademia Olimpica, which was founded there in 1555.
The Teatro Olimpico is, along with the Teatro all'antica in Sabbioneta and the Teatro Farnese in Parma, one of only three Renaissance theatres remaining in existence. Both these theatres were based, in large measure, on the Teatro Olimpico. It is still used several times a year.
Since 1994, the Teatro Olimpico, together with other Palladian buildings in and around Vicenza, has been part of the UNESCO World Heritage Site City of Vicenza and the Palladian Villas of the Veneto.
The Teatro Olimpico is the last work by Palladio, and ranks amongst his highest masterworks. The Vicentine architect had returned to his native city in 1579, bringing with him a lifetime of detailed study into all aspects of Roman architecture, and a more detailed understanding of the architecture of classical theatre than any other living person. Palladio had illustrated Daniele Barbaro's Italian translation of Vitruvius' De architectura; the prints for this edition include floorplans for Roman theatres and an elevation for the scaenae frons of Vicenza's ruined Roman theatre, the Teatro Berga. As well, Palladio's papers include plans for the imagined reconstruction of the ruined Roman theatres in Pola and Verona.
