Saint Nikola Bolnicki was built in 1313 with dormitories around them which were used as quarantine stations for visitors of Ohrid. After the coming of the Turks the structure of the city changed and they lost their purpose, so they were turned into hospitals. That is where the name Bolnicki comes from (bolnica - hospital).
The paintings on the walls of the church originate from several periods. Also the figures of St. Clement, St. Nikola and St. Pantelejmon, which are represented in life size, as well as the images of the holy warriors Theodor Tiron and Stralitat are notable. The few icons in the church are also of special value, the most significant being the litian (religious procession) icon dedicated to St. Naum.
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.
