St. Jadwiga's Church in Brzeg is a Gothic castle church. The Gothic brick-built chapel, adjoined to the south-western portion of Brzeg Castle was built in the former location of a collegiate church built between 1368 and 1369. In 1741, the chapel was destroyed due to Prussian bombardment, with only the presbytery having had survived. After its reconstruction in 1783-1784, the chapel served as the mausoleum for the Silesian Piasts (after 1945, 22 sarcophagi were found in the crypt). The chapel suffered damage during World War II, and was reconsecrated as a church in 1989.
Presently, the sarcophagi are located in the adjoined Silesian Piasts Brzeg Castle Museum.
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.
