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:Celje Castle was once the largest fortification on Slovenian territory. The first fortified building on the site (a Romanesque palace) was built in the first half of the 13th century by the Counts of Heunburg from Carinthia on the stony outcrop on the western side of the ridge where the castle stands. It had five sides, or four plus the southern side, which was a natural defence. The first written records of the castle date back to between 1125 and 1137; it was probably built by Count Gunter. In the western section of the castle, there was a building with several floors. Remains of the walls of this palatium have survived. In the eastern section, there was an enclosed courtyard with large water reservoirs. The eastern wall, which protects the castle from its most exposed side, was around three metres thicker than the rest of the curtain wall. The wall was topped with a parapet and protected walkway.
