Neuchâtel castle adjoins the collegiate church and overlooks the city. By following the circular path at the base of the outer walls, you get a general idea of the different parts of the building erected around a large courtyard and a smaller one, to the south. It can be accessed from Rue de la Collégiale or the cloisters.
The castle history dates back to the Roman age, but the first stone castle was probably built in the 11th or 12th century. It has been altered and rebuilt several times. From 1708 to 1848 it belonged to the Prussia.
The construction of the church began at the end of the 12th century and was completed in 1276. Facing the gates of the castle, the three apses are striking by the beauty of their Roman design. Only the south clock tower is ancient, the spire and the north tower being built in 1869.
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.
