Castello dell’Innominato ('the unnamed castle') history dates back to the Carolingian period. At that time on the hill of Somasca, the upper district of Vercurago, there was a signalling tower, that became a fortress some centuries later (documented in 1158). From 1454 this land felt into the clutches of the Republic of Venice and the Adda River became the natural border between the Serenissima (Venice) and the duchy of Milan.The fortress was destroyed by the French, who begun some months before a war against Venice and the bailey was shelled by the Russian in 1799 during the battle between the Napoleonic troops and the Austro-Russian.
today the stone arch, small chapel and walls remain. From the bailey you can admire the wonderful landscapes and sights on the eastern branch of Lake Como to the Alps (north) and the flow of the Adda River (south).
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.
