The settlement of Titamanninga was first mentioned about 790 AD, then a possession of St Peter's Abbey, Salzburg. After the Archbishops of Salzbug had achieved immediate status in the late 13th century, Tittmoning Castle was built as a border fortress against the incursions by the Dukes of Bavaria. The episcopal administrator of the castle and its environs was called burgrave, as was Ulrich von Wispeck in 1282. Tittmoning was occupied by the forces of the German king Louis the Bavarian during his conflict with the papacy in 1324; nevertheless, he restored it to the Salzburg archbishops three years later.
Temporarily given in pawn to Bavaria, the unlucky Prince-Archbishop Wolf Dietrich Raitenau had to cede the castle to the Bavarian duke Maximilian I in 1611; it was repurchased by his successor Archbishop Mark Sittich von Hohenems and rebuilt as a hunting lodge according to plans designed by Santino Solari. By the 17th century the castle had finally lost its character of a fortress and became the summer residence of the Prince-Archbishops. Upon the Congress of Vienna, the Rupertiwinkel region finally fell to the Kingdom of Bavaria and Tittimoning Castle, damaged by French troops during the Napoleonic Wars, passed under state-ownership.
In the early years of World War II the castle was used as a prisoner-of-war camp for officers, Oflag VII-D. British and American citizens were also interned there. Today Tittmoning castle is a museum.

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.
