The ruins of the medieval Šášov Castle stand above the river Hron. According to a legend, the lord of the Zvolen Castle had it built for his court joker who saved his life while hunting.
The task of the Šášov Castle was to guard the trade road and to collect toll. It became royal property in the 14th century and part of the dowry of the royal wives. In 1490 the family of Dóczy bought it from Queen Beatrix and reconstructed it into the Renaissance fort. The castle fell in decay after the Rebellion of Estates in 1708. Only some walls survive.
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.
