The Teatro Olimpico ('Olympic Theatre') was 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 one of only three Renaissance theatres remaining in existence. 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.
References:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
