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:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
