The Swabian Castle in Oria is a wonderful construction built between 1225 and 1233 at the behest of Holy Roman Emperor Frederick II. Over the centuries, it has been inhabited by princes, knights and noblemen. It has a triangular plan and is characterised by three towers called Quadrata (Square), Del cavaliere (of the knight) and Del Salto (Jump): the first one was built during the time of Frederick II, while the other two under the Angevin domination.
According to a local tradition, the foggy atmosphere which shrouds the castle is not just a natural phenomenon, but it recalls something which happened during the construction of the castle, known as Oria Fumosa, foggy Oria. A must-see is the castle at sunset, with an amazing picture-postcard view, which can be admired from any place in the town.
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.
