The Dubovac Castle overlooks the Croatian city Karlovac. Its square tower was probably built during the 13th century. In the 15th century, the castle was rebuilt in Renaissance style. The castle had various owners—from Slavonian nobleman family Sudar to famous Croatian counts and dukes Frankopan and Zrinski. From 1671 until 1809, the Dubovac was owned by the Karlovac generals. In 1837, a new owner, Count Laval Nugent, rebuilt the castle in the spirit of romanticism. Dubovac was once again renovated in 1952 in relation to graphics from the end of the 18th century.' There is a photograph of the castle at that site.
The castle was used for several years recently as a hotel, and the damage done to the interior to accommodate rooms is now being repaired. There are museum exhibits and a large model of the countryside. Guide materials indicate that the fortress was built on a hill constructed by the people in order to maximize defenses and views of the surrounding areas.
The castle recently was featured on a commemorative Croatian postage stamp, complete with photograph.
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.
