A 15th century hexagonal wall surrounds the medieval village of Barbara perched on a ridge of a hilly ridge stretched between the rivers Misa and Nevola.
...The village of Barbara consists of two parts: the Castle, or the fortified center of the thirteenth century surrounded by a fortified perimeter and delimited to the south by Porta Roma and to the north by the door of the arch of Santa Barbara and the Borgo, or the medieval town that from the door of the arch of Santa Barbara stretches on a slope or falls towards the neoclassical church of the Assumption. The castle, renovated in the fifteenth century is still surrounded by a wall with shoe, equipped with four corner fortifications and culminating in an imposing tower elevated, currently called “‘the Torrione”. The two small towers on the north side, those facing Via Castelfidardo, are basically intact, still have the gunners’ post, battlements or fire vents for colubrine or arquebuses; the high tower on the right of Porta Roma was instead rebuilt in the 60s in place of a previous fifteenth century tower diroccato following the bombing of the second world war. It is visible the base of a fourth house-tower, placed between the gate of the arch of Santa Barbara and Via delle Mura.
