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:Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
