Charleroi Belfry is part of the City Hall, designed by architect Joseph André in 1936. It is a perfect blend of Classicism and Art Deco. The 70-metre-high belfry can be accessed by climbing 250 stairs and was built using blue and white stone and bricks. It is crowned with a small bronze tower. The last three levels are reserved for the chambers of the 47 bells forming the carillon. Every fifteen minutes it chimes out a few bars of folk songs by Jacques Bertrand, the bard of Charleroi. This belfry is a UNESCO world heritage site.
References: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.
