Soria pro-Cathedral was built in the 12th century on the site of an old Augustine monastery, and was subsequently rebuilt in the 16th century in Renaissance style under the patronage of Bishop Acosta. The church has an open plan with three naves of equal heights, covered by vaults with star-shaped skylights. It has quite austere décor, both inside and out, except the south doorway, which is in Plateresque style, with a round arch with archivolts and a high frieze. It still conserves its 12th century Romanesque cloister.
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.
