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 ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
