It is thought that the Trsat castle lies at the exact spot of an ancient Illyrian and Roman fortress. It was owned by Frankopan family who built the present castle in the 13th century.
The capture of the Castle of Trsat compelled the Ban of Croatia, Andrew Bot of Bajna (Bajna is a village in Hungary, near Esztergom), to intervene in the Austro-Venetian war, and in June 1509 he first recaptured Trsat with his Croatian army and then entered Rijeka after expelling the Venetians. In October 1509, the Venetians withdrew for good and Rijeka returned to the possessions of Maximilian of Habsburg. This notable episode is the sole event which links Rijeka with Venice, and consequently with Italy, during the whole of its history from the 7th century on.
In the 17th century the castle fell into decay due to the receding threats from Venice and the Ottoman Empire. Its decline was accelerated by the earthquake of 1750. In the year 1811, during the Napoleonic wars, Captain Hoste in pursuit of the French, arrived with his frigate at Fiume where he made himself lieutenant-governor. The situation in Trieste soon drew him away, but in 1826 he had the satisfaction of handing the castle over to Field-Marshal Nugent, an Irishman then commanding the Austrian troops in the vicinity, for the purpose of conferring on him the rank of an Austrian noble. The general was later honoured by the Austrians and presented with the castle at Trsat as his residence. He had it restored in Neo-Gothic style and built a mausoleum adorned with the coat of arms of the Nugent family. It remained in the Nugent family until nearly the end of the Second World War when the general's great-granddaughter, Countess Nugent, died at the age of 82.
Today the castle has now been turned into a restaurant and many tourists visit the place during the summer months.
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.
