Siega Verde is an archaeological site in Serranillo, Villar de la Yegua. It was joined to the Côa Valley Paleolithic Art site in the World Heritage List in 2010.
The site consists of a series of rock carvings, discovered in 1988 by professors Manuel Santoja, during an inventory campaign of archaeological sites in the valley of the Águeda river. Subjects include equids, aurochs, deer and goats, among the most common ones, as well as bison, reindeer and the woolly rhinoceros, which were not yet extinct at the time.
The engravings date to the Gravettian culture of the Upper Palaeolithic (circa 20,000 years ago). There are also more recent, anthropomorphic representations, dating to the Magdalenian age (c. 9,000 years ago). There is a total of 91 panels, spanning some 1 kilometers of rock.
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.
