Château Saint-Léon is a former castle in the center of Eguisheim. The castle was built by the Counts of Eguisheim and taken over by the Bishop of Strasbourg during the 13th century. An episcopal bailiff occupied it until the French Revolution (1789). The enceinte was surrounded by a moat which was filled in by the 18th century. Houses built in the castle courtyard and against its walls were destroyed by a fire in 1877 which also damaged the castle - it was left in runs for many years.
In 1885, it was bought by the Bishop of Strasbourg through the mediation of a M. Stumpf who wanted to build a chapel dedicated to Saint Leo. The remains of the keep were destroyed and the chapel built in its place, the works being carried out by the architect of historic monuments, Charles Winkler. The chapel was completed in 1895. Winkler also restored the residence at the south of the site which had been rebuilt, with mullioned windows in the 16th century. He added a staircase turret and a neo-Renaissance balcony.
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.
