St.Nazaire cathedral is te main sight in Béziers. This grandiose Romanesque cathedral dates from the 13th century. It was erected on the site of an earlier building which was destroyed during the Massacre at Béziers in the Albigensian Crusade. It occupies one of the best sites in town: from the concourse in front of the cathedral there are beautiful views out over the surrounding vineyards and towards the foothills of the Massif Central to the north.
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.
