The Castle of Segonzano was built in the 13th century on a rock spur, around 100 meters above the valley. The place where it's placed was probably the site of a prehistoric hillfort. Built by Rodolfo Scancio, on the authority of the Prince-Bishop of Trento, Federico Vanga, the castle served as an important fortified site guarding the trade route passing through the Adige Valley and across the Cantilaga bridge on the river Avisio.
The fortress became hugely important between the 14th and 15th centuries. In the 14th century it was owned by the Scancio, Rottenburg and Greifenstein families and then passed, in 1424, to the Dukes of Tyrol.
When German painter Albrecht Dürer passed here on his first journey to Venice in 1494, he was so impressed by the gloomy walls of the fortress, that he dedicated two celebrated watercolours to it. In 1971, Durer's historic visit to the site was commemorated by two porphyry pillars, at Faver and Piazzo di Segonzano, marking the locations from which he was inspired to paint the two views.
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.
