The two-tiered Roman amphitheatre is probably the most prominent tourist attraction in the city of Arles, which thrived in Roman times. Built in 90 AD, the amphitheatre was capable of seating over 20,000 spectators, and was built to provide entertainment in the form of chariot races and bloody hand-to-hand battles. Today, it draws large crowds for bullfighting as well as plays and concerts in summer.
The building measures 136 m in length and 109 m wide, and features 120 arches. It has an oval arena surrounded by terraces, arcades on two levels (60 in all), bleachers, a system of galleries, drainage system in many corridors of access and staircases for a quick exit from the crowd. It was obviously inspired by the Colosseum in Rome (in 72-80), being built slightly later (in 90).
With the fall of the Empire in the 5th century, the amphitheatre became a shelter for the population and was transformed into a fortress with four towers (the southern tower is not restored). The structure encircled more than 200 houses, becoming a real town, with its public square built in the centre of the arena and two chapels, one in the centre of the building, and another one at the base of the west tower.
This new residential role continued until the late 18th century, and in 1825 through the initiative of the writer Prosper Mérimée, the change to national historical monument began. In 1826, expropriation began of the houses built within the building, which ended by 1830 when the first event was organized in the arena - a race of the bulls to celebrate the taking of Algiers.
Arles Amphitheatre is listed as a UNESCO World Heritage Site, together with other Roman buildings of the city, as part of the Arles, Roman and Romanesque Monuments group.
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.
