Muravanka Fortified Church was built between 1516 and 1542. Together with earlier Suprasl' and Synkavichy churches it represents an original class of church-fortresses that appeared in Belarus in 15th-16th centuries.These are compact in plan, rectangular buildings flanked in the corners with towers. The top of the walls are fortified with mashykooli and shooting windows. There were cellars in the basement with water and food for the sieged defenders.
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.
