The Pont Julien is a Roman stone arch bridge over the Calavon river, in the south-east of France, dating from 3 BC. The supporting columns are notable for openings to allow floodwater to pass through. It is located in the territory of the commune of Bonnieux, north of the village of the same name, and 8 km west of Apt. Originally, it was built on the Via Domitia, an important Roman road which connected Italy to the Roman territories in France. It was used for car traffic until 2005, when a replacement bridge was built to preserve it from wear and tear. It is still used as bike- and footpath. This amounts to approximately 2000 years of uninterrupted use.
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.
