Nobbin village is best known for the megalithic tomb known as the Riesenberg. The tomb was constructed of glacial erratic boulders and dates back to the New Stone Age in Rügen. It is one of the largest stone graves in North Germany and lies just a few metres from the steep coast on the bay of Tromper Wiek, immediately by the cliff top path.
The trapezoidal enclosure, which originally had 53 large boundary stones, is 34 metres long and 8 to 11 metres wide (39 stones have survived). In the north-east were two transverse dolmens, of which only one is well preserved. It is 1.4 metres high, 1.8 metres long and 1.1 metres wide. On the southwest side two guardian stones in front of the enclosure rise to a height of over 3 metres, otherwise they are typical, especially of Scandinavian dolmens, but also similar in dimensions to the Dolmens of Dwasieden and those in Dummertevitz on Rügen. The presence of guardian stones is rare in Germany, but is explained by the proximity of the site to the Danish islands.
During excavations in 1970 by Ewald Schuldt, Neolithic finds were made: three crosscutting arrowheads, a sword, some broken vessels and a few bone fragments (including two skulls). In the northern grave chamber were the remains of an urn burial from the 5th century BC. Between the guardian stones were shards of pottery from the Slavic era Rani tribe and an Arabic silver coin from the 9th century, amongst other things.
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.
