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:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
