The town hall in Vilnius was mentioned for the first time in 1432. Initially it was a Gothic style building, and has since been reconstructed many times. The current Vilnius Town Hall was rebuilt in neoclassical style according to the design by Laurynas Gucevičius in 1799. It has remained unchanged since then. Its Gothic cellars have been preserved and may be visited. Nowadays it is used for representational purposes as well as during the visits of foreign state officials and rulers. The Town Hall Square at the end of the Pilies Street is a traditional centre of trade and events in Vilnius.
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.
