The Roman amphitheatre in Brescia is located immediately at east of the Capitolium. It has been built in the Flavian era and altered in the 3rd century. With its 86 meters diameter, is one of the largest Roman theatres in northern Italy and originally it housed around 15,000 spectators.
In the 5th century, an earthquake has heavily damaged the building. In addition, in later centuries, its remains were incorporated into new buildings built on top of it, largely demolished starting from the 19th century. Of the original structure are preserved the semicircular perimeter walls, the two side passages (aditus) and the remains of the proscenium, as well as many fragments of columns and friezes of the scaenae frons. The most of the orchestra and the ima cavea are still below ground. The archaeological excavations should resume in the coming years.
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.
