Ostuni Cathedral was originally a church practising Orthodox rites prior to the year 1000. In 1228-1229, the present Romanesque church was erected by Frederick II of Swabia. The earthquake of 1456, strongly felt in Brindisi, damaged it. During 1469-1495 it was again rebuilt in a Gothic style.
The façade acquired its elegant rose window in the 15th century. The church once had four such windows. One of the portals is dedicated to Saint Blaise (San Biagio), one of the patrons of the city, and has the saint carved on the portal. A restoration in the 1970s tried to remove stucco decorations that covered the original Romanesque and Gothic architecture.
The interior has a number of artworks that covered the ceiling and altars. The Chapel of the Sacred Heart, once of St Cajetan (Gaetano) had a canvas of the saint attributed to Domenico Antonio Vaccaro. The Cappellone dell'Immacolata was decorated in the 18th century. The sacristy has a large venerated icon depicting Saint Oronzo. One Chapel is dedicated to the patron saints of Ostuni: Saint Blaise, Saint Augustine, Saint Orontius, and Saint Irene. The church once had a canvas, now stolen, of Santa Lucia by Palma il Giovane. The apse has an altarpiece of the Assunta, and the chapel of Santa Maria della Sanità has a fresco depicting Saint Catherine of Alexandria. A niche of the counter-facade has a 15th-century statue of Christ.
The cathedral archives hold nearly 200 parchments dating to the 12th century.
In 1986 it became a co-cathedral of the Archdiocese of Brindisi-Ostuni, and in 2011 was granted the status of a minor basilica.
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.
