The remains of the Roman town of Regina Turdulorum, found near the municipality of Casas de Reina in Badajoz province, form an extremely interesting ensemble, in a perfect state of preservation, with the forum and a 1st century AD theatre as its most remarkable features.
The Roman theatre was built in the age of the Flavian emperors, could seat one thousand spectators and was operational until the 4th century AD.
Meanwhile Regina's Roman forum preserves the foundations of some houses, civil buildings, porticoes and the odd remnants of paving or Roman road that transport you directly to this period of history. A porticoed templum with a small room dedicated to the worship of the emperor and the imperial house has also been recovered through different excavations, alongside which other buildings must have existed, such as the market and the basilica.
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.
