The Hôtel de Ville is the city hall of Lyon and one of the largest historic buildings in the city. In the 17th century, Lyon was developed and the Presqu'île became the city center with the place of Terreaux, and the Lyon City Hall was built between 1645 and 1651 by Simon Maupin.
Following a fire in 1674, the building was restored and modified, including its facade, designed by Jules Hardouin-Mansart and his pupil Robert de Cotte. In 1792 during the French Revolution, the half-relief of Louis XIV on horseback, in the middle of the facade was removed and replaced only during the Restoration by Henry IV of France, in the same posture.
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.
