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:House of the Blackheads (Melngalvju nams) is a building situated in the old town of Riga. The original building was erected during the first third of the 14th century for the Brotherhood of Blackheads, a guild for unmarried German merchants in Riga. Major works were done in the years 1580 and 1886, adding most of the ornaments.
The structure was bombed to a ruin by the Germans June 28, 1941 and the remains demolished by the Soviets in 1948. The current reconstruction was erected from 1995 to 1999. Today the House of Blackheads serves as a museum and sometimes concert hall.
