Ľubovňa Castle was built after 1292 by the Hungarian King Andrew III. As a border guard castle, it protected trade routes to Poland. Famous Hungarian and Polish noble families entered its history. The castle was the seat of the Polish trustees from the Spiš region for more than 350 years. Hungarian and Polish Kings and Queens, such as Mary, Sigismund, Vladislav II Jagiełło, John Albrecht, John Casimir, John Sobieski, honored the castle by their visit. Between 1655 and 1661 Polish crown jewels were hidden in the castle. Today their replicas - crown, apple, scepter and coronation mantle of Stanislaw August Poniatowski are exposed in the castle chapel. Famous adventurer Moric Beňovský who eventually became the king of Madagascar got to know the castle prison in 1768. One of the most valuable objects of the castle is definitely the main castle tower (Nebojsa) which has been preserved since the medieval era. There is an outlook tower with 360 degree view of the surroundings on the sixth floor. Just below the castle there is a unique natural museum that is definitely worth visiting.
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.
