The Genoese Citadel is the main part of the town of Calvi, and its most important historical monument. It was a military outpost in the 15th century that helped guard the city against attacks from Franco-Turkish raiders to Anglo-Corsican armies. Inside the battlements, don’t miss the well-proportioned Caserne Sampiero, a military barracks that once served as the Genoese administration's seat of power, and the 13th-century Cathédrale St-Jean Baptiste, whose most celebrated relic is the ebony Christ des Miracles, credited with saving Calvi from Saracen invasion in 1553.
The citadel sits high above Calvi port from where it towers over the sea. From up here you get some great views of the coast and harbour.
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.
