Altamura - Cattedrale di Santa Maria Assunta

The area around the modern Altamura (pop 70.000) was inhabited in early times. There are Bronze Age tumuli and between the 6th and the 3rd century BC a massive line of megalithic walls was erected. This (later Roman) city was inhabited until the 10th century when it was reportedly looted by Saracens. A couple of centuries after Altamura was reportedly looted by the Saracens, it started to be inhabited again as Emperor Frederick II refounded the city (1232) and ordered the construction of the large Altamura Cathedral, which became one of the most venerated sanctuaries in Apulia.

Altamura was ruled by various feudal families, including the Orsini del Balzo and the Farnese (1538–1734), the latter responsible for the construction of numerous palaces and churches. In the past, Altamura also had a large castle, whose construction dated back to the 11th-13th century, which has been completely demolished.

Altamura Cathedral (Cattedrale di Santa Maria Assunta) is probably the only church that was ever founded by Frederick II. In 1248, under pressure from Frederick, Pope Innocent IV declared Altamura exempt from the jurisdiction of the bishop of Bari, making it a "palatine church", that is the equivalent of a palace chapel. After heavy damage chaused by an earthquake in 1316 it was renovated by Robert of Anjou.

Major changes were made to the cathedral in 1534, including switching the front and back around! The cathedral's main facade originally faced west but it now faces east. The Gothic window of the apse, which had been in place since 1232, was moved to the left side to make room for the rose window, that dominates the facade.
