The Angevin Keep is the magnificent survivor of the set of towers and bastions that surrounded the medieval town of Bitonto.
Built in about the middle of the sec.
XIV°, as a work commissioned by the Angevins to restore and strengthen the Bitonto city walls on the northern side with a defensive system more responsive to the new technique of warfare.
The keep, identified as the Tower of Porta Baresana, was the largest and best equipped to deter the raids of aggressors, garrisoned by a militia armed by a castellan, from which it derived the name “Castle.”
The external layout of the mighty artifact has remained intact through the six centuries of its tormented history, coming down to us mutilated in the basement part, where the ramparts and dependent defense and service works stood.
Its cylindrical shape is that regularly used by the Angevins for fortifications, as in the castles of Conversano and Manfredonia.
