Ostuni Co-cathedral

The current Oria Cathedral is due to Bishop Castrese Scaja who, in 1750, demolished the previous medieval Romanesque church (threatened with collapse after the earthquake of 20 February 1743) and built the new cathedral in Baroque style. During the construction of the new Baroque cathedral, designed by the architect Giustino Lombardi, two green marble columns of the old Romanesque cathedral were purchased for 8000 ducats by the King of Naples to embellish the chapel of the royal palace of Caserta. Of particular interest is the 16th-century "crypt of the mummies" located under the building.

The Church of Santa Maria del Casale is a Romanesque-Gothic church erected at the end of the 13th century on the site of a chapel that contained a venerated Marian icon. In 1811 the church was removed under Murat and was used as barracks. The Franciscans returned there in 1824 and tried to repair the very serious damage. The building was recently restored by the missionaries of the Consolata of Turin, who settled in the nearby 16th century convent.

The church of San Benedetto is a sacred Romanesque building probably dating back to the 10th century. On the right stands the massive Romanesque bell tower from the 11th century. The interior, recently restored again, is presented in the 11th-12th century redefinition. The Romanesque cloister is also worth a visit.
