Bisceglie Castle was originally a tower built around 1060-1070 by Normans and enlarged in the 13th century by Swabian counts. The tower was made later higher by the Angevines. Originally the castle was a four-sided building with five towers; today there are three towers left. The North-East tower is adjacent to the 12th century St Giovanni in Castro Church, which was included in the castle as its chapel during the Angevin time. Today the castle hosts an ethnographic museum.
Château de Niort is a medieval castle in the French town of Niort. It consists of two square towers, linked by a 15th-century building and dominates the Sèvre Niortaise valley.
The two donjons are the only remaining part of the castle. The castle was started by Henry II Plantagenet in the 12th century and completed by Richard the Lionheart. It was defended by a rectangular curtain wall and was damaged during the Wars of Religion. In the 18th century, the castle served as a prison.
The present keeps were the central point of a massive fortress. The southern keep is 28m tall, reinforced with turrets. The northern tower is slightly shorter at 23m. Both are flanked with circular turrets at the corners as well as semicircular buttresses. Each of the towers has a spiral staircase serving the upper floors. The Romanesque architecture is of a high quality with the dressed stones closely jointed.
