Dobczyce Castle was first mentioned in written sources in 1362, but had been fortified since 1311. In the time of Casimir III the Great, the walls were from 5 to 9 meters thick, and the castle was a fortified stronghold. In 1398, the castle was the abode of King Władysław II Jagiełło and his wife Jadwiga. In 1473, for several months, Prince Casimir stayed here after returning from an unsuccessful expedition.
The Lubomirski family, who ruled the castle from 1585, rebuilt the Gothic fortress into a Renaissance residence in the years 1593-1594. The clocktower, chapel and fountain were added. By 1620 the castle had 70 rooms and 3 towers. In the 1960s the site was extensively excavated.
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.
