The St. John's Church in the Hamina city centre was built in 1841-1843. It was designed by famous architect Carl Ludvig Engel and represents the Neoclassicism style with strong influence of Greece temples.
Before the present church there was a church of Ulrika Eleanora (built in 1732, destroyed by fire in 1742) and the commandant’s house. The residence of the fortress commander was the place where the Russian negotiators lived and signed the Treaty of Hamina (after the Finnish War in 1809).
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.
