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: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.
