The undisputed symbol of Montegalda is the ancient castle which dominates the entire plain, one lucky survivor of the three manors, two of which stood in Montegaldella and Cervarese S. Croce. The building changed over the years and in the 18th century it was transformed from a military facility into a Venetian villa. Its foundation dates back probably to 1176 but in the courtyard a foundation of the Roman period was found, which anticipates that construction. The castle is undoubtedly impressive, marked by three towers, a keep and the crenellated ring-shaped walls of the Guelph form, which would host the famous 'trabocchetto' (trap door) to thwart the invaders. After the tyrant Ezzelino da Romano in 1300, the domain of the castle passed to the dominion of the Scala family of Verona and later, in 18th century it was transformed into a Venetian villa. The castle of Montegalda now seems to have regained its former glory thanks to a meticulous restoration, reflecting the still incredible charm and mystery.
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.
