The Church of St. Bartholomew in Kolín is a significant Gothic religious building. The early Gothic church was probably founded shortly after the establishment of the royal town of Kolín in the mid-13th century. Archaeological finds indicate that there was already another church on its site before. The founder and builder was probably King Přemysl Otakar II. The construction was initially led by the Přemyslid building guild. It was based on contemporary Saxon, Thuringian, and northern French models. The construction was completed before 1300 with the construction of two slender octagonal towers on the western façade.
In 1349, the church burned down. To restore it, Charles IV summoned his court architect, Peter Parler, in 1360. At that time, he was already supervising the construction of St. Vitus Cathedral in Prague. In Kolín, he started building a new, high choir on the site of the original presbytery. The restored church was consecrated in 1378.
In the late 15th century, the ringing of the north tower disrupted the statics. Therefore, in 1504, a separately standing octagonal bell tower was added, where the bells from the damaged tower were transferred. Until 1756, they were hung upside down. In 1728, a clock, first mentioned in 1494, was transferred to the wall of the bell tower.
On the south tower hung (probably from 1442) the legendary Vužan bell, cast from bell metal with a high proportion of silver and equipped with a band of pure gold. It was subject to special security measures and guarded as one of the city's greatest treasures. However, it was destroyed in a major city fire in 1796. At that time, the clock was also destroyed, and the interior of the church was damaged.
In the second half of the 19th century, architect Josef Mocker led an extensive puristic reconstruction of the church (similarly to St. Vitus Cathedral in Prague or Karlštejn Castle). For this purpose, the Society for the Completion of the Dean's Church in Kolín was founded in 1878. The restoration was completed in 1910. In 1945, the church was damaged by a bomb explosion during an air raid. A general reconstruction began in 1963 and continues to this day. In 1995, the church complex was declared a national cultural monument.
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.
