Tolmin Castle was first mentioned in 1188, and its chapel of Saint Martin in 1194. The east and north towers appear to have formed the original core of the fortress; another two hexagonal towers were added later. The north tower had an extensive basement for the storage of provisions, which along with two wells and rainwater cisterns allowed for the withstanding of sieges.
The castle was held in fief by a long series of masters: the Patriarchate of Aquileia, the Counts of Gorizia, the city of Cividale del Friuli, the Venetian Republic, and finally the Habsburgs. It appears to have functioned as a dedicated fortress rather than a residence, and had no permanent civilian population in peacetime, only a large garrison; it also housed a prison. The structure was severely damaged in the earthquakes of 1348 and 1511, but was repaired each time. It was finally abandoned in 1651 by its last owners, the Coronnini family, for a new manor in Tolmin itself, though it remained sufficiently intact by 1713 to play a role in the great peasant revolt of that year. The castle is currently in ruins, though parts of it have been restored.
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.
