Monfalcone Castle, locally known as Rocca di Monfalcone or Castello di Monfalcone, lies on a mountain north of the town with the same name. Originally a prehistoric fortified village, the site was occupied by a Roman observation tower, guarding the road from the town of Aquileia to Trieste, and later by a fortress dating back to the reign of Theoderic the Great (around 490 AD).
As a stronghold of the Patriarch of Aquileia, overseeing the County of Duino, the castle was long contended for by the Patriarch and the Count of Gorizia, but was also a 'free commune' holding a seat in the Friulian Parliament.
Having surrendered on 14 July 1420 to the troops of the Venetian doge, Tommaso Mocenigo, it became an important outpost for the protection of the Venetian mainland against the Count of Gorizia and the Austrian Emperor and a defence against the attacks of the Turks.
In 1797 it came under Austrian rule and on 9 June 1915 it was occupied by the Italian army.
The castle is a square keep surrounded by a circular wall and a low earthen wall.
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.
