Bydlin Castle was built in the 14th century and appears in documents after 1389. The builder of the castle was probably Niemierza of Strzała or his father Pełka. At the end of the 15th century the stronghold became the Brzezickis’ property, and then the Szczepanoskis’ and the Boners’. In the second half of the 16th century Jan Firlej transformed the castle into the Arian Protestant Church, and at the end of the 16th cent. his son, Mikołaj Firlej, converted it into the Catholic Church of the Holy Cross. The building was abandoned at the end of the 18th century due to escalating assaults of the brigands and since then it has been falling into ruin.
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.
