The Admiralty building is the former headquarters of the Admiralty Board and the Imperial Russian Navy and since 2012 once again the headquarters of the Russian Navy.The building was re-built in the 19th century to support the Tsar's maritime ambitions. The original design was a fortified shipyard which was later surrounded by five bastions and further protected by a moat.
The Empire Style edifice visible today lining the Admiralty Quay was constructed to Andreyan Zakharov's design between 1806 and 1823. Located at the western end of the Nevsky Prospekt, The Admiralty with its gilded spire topped by a golden weather-vane in the shape of a small sail warship (Korablik), is one of the city's most conspicuous landmarks and the focal point of old St. Petersburg's three main streets - Nevsky Prospect, Gorokhovaya Street, and Voznesensky Prospect - underscoring the importance Peter I placed on Russia's Navy.
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.
