Duomo di Ostuni (Ostuni Cathedral), Ostuni (must see)

Ostuni Cathedral or Cathedral Basilica of Santa Maria Assunta, is dedicated to the Assumption of the Virgin Mary and holds a rich history. In 1228-1229, under the patronage of Frederick II of Swabia, the cathedral took on its present Romanesque architectural style. It was primarily constructed using pietra gentile, a local stone.

In 1456, an earthquake severely affected the region, including the cathedral. Following this disaster, from 1469 to 1495, the cathedral underwent a thorough reconstruction, embracing a Gothic architectural style.

The cathedral's façade boasts an elegant rose window, a characteristic feature from the 15th century. At one point, there were four such windows gracing the exterior. A notable portal within the façade is dedicated to Saint Blaise (San Biagio), one of the city's beloved patrons, and showcases a finely carved image of the saint.

Inside the cathedral, visitors are treated to a wealth of artistic treasures adorning the ceiling and altars. The Chapel of the Sacred Heart, once dedicated to Saint Cajetan (Gaetano), features a canvas attributed to Domenico Antonio Vaccaro portraying the saint. The Cappellone dell'Immacolata underwent embellishment during the 18th century. The sacristy houses a sizable venerated icon depicting Saint Oronzo.

Additionally, there is a chapel dedicated to the patron saints of Ostuni, namely Saint Blaise, Saint Augustine, Saint Orontius, and Saint Irene. The cathedral once possessed a painting of Santa Lucia by Palma il Giovane, which regrettably was stolen. In the apse, an altarpiece of the Assunta takes center stage, while the chapel of Santa Maria della Sanità features a fresco depicting Saint Catherine of Alexandria. A niche on the counter-façade cradles a 15th-century statue of Christ.

The cathedral's archives are a treasure trove of nearly 200 parchments dating back to the 12th century, providing valuable historical insights.

Recognizing its architectural and historical significance, Ostuni Cathedral was declared a National Monument in 1902.
