The Swabian Castle in Oria is a wonderful construction built between 1225 and 1233 at the behest of Holy Roman Emperor Frederick II. Over the centuries, it has been inhabited by princes, knights and noblemen. It has a triangular plan and is characterised by three towers called Quadrata (Square), Del cavaliere (of the knight) and Del Salto (Jump): the first one was built during the time of Frederick II, while the other two under the Angevin domination.
According to a local tradition, the foggy atmosphere which shrouds the castle is not just a natural phenomenon, but it recalls something which happened during the construction of the castle, known as Oria Fumosa, foggy Oria. A must-see is the castle at sunset, with an amazing picture-postcard view, which can be admired from any place in the town.
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.
