The Amphitheatre of Mérida is situated in the Roman colony of Emerita Augusta, present-day Mérida, in Spain. The city itself, Emerita Augusta, was founded in 25 BC by Augustus, to resettle emeritus soldiers discharged from the Roman army from two veteran legions of the Cantabrian Wars (the Legio V Alaudae and Legio X Gemina). The amphitheatre itself was completed in 8 BC. The term emeritus refers to the soldiers, all of whom had been honorably discharged from service.
The amphitheatre had a capacity of approximately 15,000 spectators and had supporting stairs and hallways (scalae) that connected the different parts internally.
The amphitheatre is part of the Archaeological Ensemble of Mérida, which is one of the largest and most extensive archaeological sites in Spain. It was declared a World Heritage Site by UNESCO in 1993.
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.
