Concattedrale Gran Madre di Dio, Taranto

The existence of the Cathedral of Taranto was confirmed in the 7th century, but it was probably demolished to make way for a new cathedral in the 11th century. However, the old construction was not completely replaced: the longitudinal arm, enlarged and lowered, incorporated the nave with the deep apse of the Byzantine church, which remained unchanged; the altar was placed under the dome and the old nave became the transept, which was then cut off from the side naves, leaving a series of small columns that decorated the old construction. In 1713 the Baroque façade was added, the work of the Lecce architect Mauro Manieri.

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 Assunta is the cathedral of Castellaneta. The original church, dedicated to the town's patron saint, Saint Nicholas, was built in the second half of the 11th century and rebuilt in the 14th century in the Apulian Romanesque style with the new dedication to Saint Mary of the Assumption. In the 17th and 18th centuries, the building was renovated and restored in Baroque style, which almost completely erased all traces of the original church.
