The Arena of Nîmes is a Roman amphitheatre built around AD 70. It was remodelled in 1863 to serve as a bullring. The Arenas of Nîmes is the site of two annual bullfights during the Feria de Nîmes, and it is also used for other public events. The building encloses an elliptical central space 133 m long by 101 m wide. It is ringed by 34 rows of seats supported by a vaulted construction. It has a capacity of 16,300 spectators.
As the Roman Empire fell, the amphitheatre was fortified by the Visigoths and was surrounded by a wall. During the turbulent years that followed the collapse of Visigoth power in Hispania and Septimania, not to mention the Muslim invasion and subsequent conquest by the French kings in the mid eighth century, the viscounts of Nîmes constructed a fortified palace within the amphitheater. In 737, after failing to seize Narbonne, Charles Martel destroyed a number of Septimanian cities on his way north, including Nîmes and its amphitheatre, as asserted in the Continuations of Fredegar. Later a small neighbourhood developed within its confines, complete with one hundred denizens and two chapels. Seven hundred people lived within the amphitheatre during the apex of its service as an enclosed community. The buildings remained in the amphitheatre until the eighteenth century, when the decision was made to convert the amphitheatre into its present form.
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.
