The Castle of Segonzano was built in the 13th century on a rock spur, around 100 meters above the valley. The place where it's placed was probably the site of a prehistoric hillfort. Built by Rodolfo Scancio, on the authority of the Prince-Bishop of Trento, Federico Vanga, the castle served as an important fortified site guarding the trade route passing through the Adige Valley and across the Cantilaga bridge on the river Avisio.
The fortress became hugely important between the 14th and 15th centuries. In the 14th century it was owned by the Scancio, Rottenburg and Greifenstein families and then passed, in 1424, to the Dukes of Tyrol.
When German painter Albrecht Dürer passed here on his first journey to Venice in 1494, he was so impressed by the gloomy walls of the fortress, that he dedicated two celebrated watercolours to it. In 1971, Durer's historic visit to the site was commemorated by two porphyry pillars, at Faver and Piazzo di Segonzano, marking the locations from which he was inspired to paint the two views.
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.
