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:The Gravensteen is a castle in Ghent originating from the Middle Ages. The name means 'castle of the counts' in Dutch. Arnulf I (918–965), Count of Flanders, was the first to fortify this place, building a medieval bastion on this high sand dune, naturally protected by the river Leie and its marshy banks. This bastion consisted of a central wooden building and several surrounding buildings, also in wood.
In the early 11th century, the wooden building was replaced by a stone residence, consisting of three large halls that made up three storeys, connected by a stone stairwell. The monumental stone staircase, the light openings, the fireplaces built into the walls and the latrines were signs of considerable luxury and comfort in those days. There was probably also a tower.
