Toritto. Some of the communal territory are included in the Alta Murgia National Park. Main sights Altamura's main landmark is the Romanesque cathedral, begun in 1232 by Frederick II and restored in 1330 and 1521–47. It is one of the four Palatine churches of Apulia, the others being the cathedral of Acquaviva delle Fonti, the Basilica of San Nicola in Bari and the church of Monte Sant'Angelo sul Gargano. The construction is influenced by that of Bari, but also with strong Gothic influences typical of the time of Frederick II. The orientation of the construction was probably changed during the 14th century restoration, to which also belongs the northern portal opening on the square; a second bell tower, the altar area and the sacristy are instead from the 16th century. Externally, the main features are the rose window, with 15 small columns radially intermingling, and the Gothic portal, set into the entrance portico standing on two stone lions. On the arch of portals are sculpted 22 panels with scenes from Jesus' life. The interior, with a nave and two aisles, has stone presepe by Altobello Persio (1587). The medieval walls, erected by Frederick II, rest upon the megalithic walls of an ancient city of unknown name. These early walls are of rough blocks of stone without mortar. Ancient tombs with fragments of vases and terracottas have also been found, of which there is a collection at the Museo Archeologico Statale di Altamura. There are caves which have been used as primitive tombs or dwellings, and a group of some fifty tumuli near Altamura. Some thirty thousand dinosaur footprints were discovered in 1999 in Altamura's territory named "contrada Pontrelli", making it a major site for the study of dinosaurs. Events A three-day renaissance fair called Federicus is held every year in the city, usually on the last weekend of April.
