Rzeszów Castle - one of the main landmarks of Rzeszów rebuilt between 1902-1906, located on the former grounds of the castle of the House of Lubomirski. Currently the castle houses the seat of the provincial court, the building housed a prison up until 1981.
An early fortress stood on the castle's grounds since the sixteenth century. At the end of the same century, Mikołaj Spytek Ligęza built a Motte-and-bailey castle close by to the current castle's location. In 1620 he expanded the castle into a 'Palazzo in fortezza'. Since 1637 the castle was put under the ownership of the House of Lubomirski. Most of the building works were done by Tylman van Gameren and Karol Henryk Wiedemann. In 1820 the complex was brought under Austrian authorities; which adapted the building for a courthouse and a prison. The building was deconstructed at the beginning of the twentieth century due to its poor state. The only parts left from the original complex are the gatehouse and bastion fortifications.
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.
