Bisceglie is located in an area inhabited since the prehistoric times, evidenced by various traces found in the area, such as the Dolmen della Chianca, where fragments of vases, pottery and human remains have been retrieved, and the Dolmen di Albarosa.

The settlement was founded by the Normans in XI century. In 1060, the first fortification was built on request of the Earl of Trani; whilst the castle was edified by the Suebi and embellished and enlarged during the Anjou domination. It has a rectangular shape with square shaped tower at each corner. The lower floor is one large stable area, whilst the first floor were the living quarters. Today the Norman Tower of Bisceglie is the seat of the local ethnographic museum and on the higher floor there is an exhibition room of the local Sacred Arts.

The Cathedral, entitled to San Pietro, in Apulian-Romanesque style, was built in 1073 at will of the Norman Earl Pietro II; the construction ended in 1295. Between the '700 and '800 the Romanesque architectural style of the Cathedral was embellished with Baroque style ornaments to give to the building the splendour of the Basilica of San Pietro in Rome. Arched windows were opened in the nave, the brick roof was demolished to give space to a central dome and the ledges and the capitals of the arches were modified. A marble floor was relayed on the pre-existing one. Of interest are the entrance portal and the wooden choir.

The Church of Santa Margherita, in original Romanesque style, as the building did not submit any style changes; features a rectangular shaped building with a central dome and barrel vaults. The hut shape façade proposes a small rose window and a series of ornamental arches

The Church of Sant'Adoeno, entitled to the Norman patron, was built in 1074 in local dark stone. Even though the building submitted damages over the centuries, the façade and the rose window still offer their original features.
