The Corderie Royale International de la mer is a vast museum complex located in the heart of the maritime Arsenal de Rochefort. The Corderie Royal is one of the most important buildings in the arsenal and was one of the first built when the city was founded in 1666.
For nearly two hundred years, the building, which is more than 374 metres long, was used to furnish the rigging (or cordage) of the French Navy. The length of the central building corresponded to the manufacture of a rope of a single cable length.
In 1926, it was decided to close the Rochefort arsenal, with the consequent gradual abandonment of the Corderie. Today it is home to the International Sea Centre, is a vast museum space that is part of the Arsenal de Rochefort (Grand Arsenal) in Rochefort, France, the city's historic, cultural and tourist landmark, which also includes the Musée National de la Marine (National Naval Museum), the construction site of the replica of the frigate Hermione, and the renovation project of the Office of the Commissioner of the Navy on Rochefort's food wharf.
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.
