Bitonto Cathedral, dedicated to Saint Mary, was the seat of the small Bishopric of Bitonto from the bishopric's foundation, believed to be in the 8th century, until 1818, when it was combined with the neighbouring Diocese of Ruvo to form the Diocese of Ruvo e Bitonto. This was separated again in 1982, and the Diocese of Bitonto, with Bitonto Cathedral as its seat, was briefly revived, but was combined with the Archdiocese of Bari in 1986 to form the Archdiocese of Bari-Bitonto, in which Bitonto Cathedral is now a co-cathedral.
The remains of a palaeochristian church, which predates by some centuries the establishment of the bishopric, have been discovered underneath the present building.
The existing church however is a Romanesque building of the late 11th-12th centuries, influenced by the Basilica of San Nicola in Bari. The west front is divided into three parts and has three portals (the central one of which is sculpted with plant motifs and scenes from the Old Testament), four mullioned windows and a rose window flanked by sculptures of animals supported by small columns. The interior has a nave and two aisles, and is also notable for its sculpture. The main artwork is the marble ambo, a combined pulpit and lectern, of 1229, a masterpiece of medieval Apulian stonecarving. In the crypt is a tile of a griffin, a survival from the predecessor church building.
References:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
