Castello Cova was built between 1910 and 1915 on a design by architect Adolfo Coppedè (brother of the more famous Gino Coppedè), it is an example of Gothic Revival architecture, with guelph-style merlons decorating the external rusticated walls as well as the middle-ages styled tower. The tower of Castello Cova was reportedly an inspiration for the architects of the Velasca Tower, a landmark skyscraper in the centre of Milan. The Pusterla di Sant'Ambrogio, an ancient postern of the Medieval walls of Milan facing Castello Cova, was recreated in the late 1930s in a style that matches the Revival style of the Castello.
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.
