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:The Basilica of Santa Maria in Trastevere is one of the oldest churches of Rome. The basic floor plan and wall structure of the church date back to the 340s, and much of the structure to 1140-43. The first sanctuary was built in 221 and 227 by Pope Callixtus I and later completed by Pope Julius I.
The inscription on the episcopal throne states that this is the first church in Rome dedicated to Mary, mother of Jesus, although some claim that privilege belongs to the Basilica di Santa Maria Maggiore. A Christian house-church was founded here about 220 by Pope Saint Callixtus I (217-222) on the site of the Taberna meritoria, a refuge for retired soldiers. The area was made available for Christian use by Emperor Alexander Severus when he settled a dispute between the Christians and tavern-keepers.
The church underwent two restorations in the fifth and eighth centuries and in 1140-43 it was re-erected on its old foundations under Pope Innocent II.
