Castello dell’Innominato ('the unnamed castle') history dates back to the Carolingian period. At that time on the hill of Somasca, the upper district of Vercurago, there was a signalling tower, that became a fortress some centuries later (documented in 1158). From 1454 this land felt into the clutches of the Republic of Venice and the Adda River became the natural border between the Serenissima (Venice) and the duchy of Milan.The fortress was destroyed by the French, who begun some months before a war against Venice and the bailey was shelled by the Russian in 1799 during the battle between the Napoleonic troops and the Austro-Russian.
today the stone arch, small chapel and walls remain. From the bailey you can admire the wonderful landscapes and sights on the eastern branch of Lake Como to the Alps (north) and the flow of the Adda River (south).
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.
