Modica Castle is located on the top of a small mountain. For a long time it was the political center of the Modica County, inhabited first by the counts and then by the governors, who succeeded each other without ever changing the Castle with other administrative offices. The current structure can be widely visited, although some points have been destroyed over time, still leaving some remains thanks to which it was possible to reconstruct important pages of the history of Modica.
The first construction of the Modica Castle dates back to 8th century, built not only to host the reigning family, but also for military and prison uses. Unfortunately, little remains of the 5 original towers and of the entire walls that surrounded the fortress of Modica, destroyed over time, also due to the earthquake of 1693.
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.
