The Collegiate Church of St. Florian was built between 1185 and 1216. It was burnt down many times in the 12th, 16th and 17th centuries. Notably, during the Swedish siege of Kraków, General Stefan Czarniecki ordered the city's suburbs burned down. However, during the city-wide fire which consumed a considerable part of Kraków in 1528, the church – containing St. Florian's relics – survived. Since then St. Florian, usually portrayed as a Roman legion officer carrying water, has been revered in Poland as patron saint of firefighters and chimneysweeps. The church's present appearance is the result of a Baroque renovation after the Polish-Swedish wars.
Since the 16th century the Church has been the University Collegiate. The coronation route began there, with the rector of the university senate welcoming new kings. The Church was also the starting point for royal funeral processions to Wawel Cathedral.
In 1667 the remains of Queen Ludwika Maria Gonzaga, wife of King Jan II Kazimierz, were placed there temporarily, and in 1818 the remains of Tadeusz Kościuszko were placed there. From 17 September 1949 to September 1951, Father Karol Wojtyła, who later became Pope John Paul II, worked there as a vicar. As Pope, in 1999 he elevated the Church to a minor basilica.
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.
