Irsina Cathedral is a Roman Catholic cathedral dedicated to the Assumption of the Blessed Virgin Mary, located in Irsina in the region of Basilicata, Italy. Since 1977 it has been a co-cathedral of the Archdiocese of Matera-Irsina, and was previously, from 1818, a co-cathedral of the Diocese of Gravina-Irsina. Before that it was the seat of the Diocese of Montepeloso. The present building was constructed in the 13th century and remodelled in 1777. It has a Baroque façade and a Gothic campanile. It contains a baptismal font of red marble and a number of 18th-century paintings of the Neapolitan School.
The cathedral also contains a well-known marble statue of Saint Euphemia. This has been attributed by some critics to Mantegna, and was exhibited as his at Mantua in 2009. Others however, including Giovanni Agosti, curator of the Mantegna exhibition at the Louvre, attribute it to Pietro Lombardo. The discussion continues.
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.
