The Lancken-Granitz dolmens are a group of seven megalith tombs in the Lancken-Granitz municipality on Rügen. Erected during the middle Neolithic, when they were used by the Funnelbeaker culture, at least some were in use until the early Bronze Age. Three of them are encircled by solitary rocks forming either rectangles or a stone circle, one has a solitary 'guardian stone' on its eastern side.
The dolmens were constructed from glacial erratic boulders and red sandstone. In part subdivided into up to four compartments as common for the region, one dolmen showed a subdivision into six such compartments, which is an unusually high number. When the tombs were archaeologically assessed in 1969, Stone and Bronze Age funerary goods were retrieved, including flint hatches, stone axes, amber pearls, bronze needles and necklaces as well as an abundance of arrowheads and pottery.
The dolmens are part of a series built between 3,500 and 3,200 BC, during the Neolithic. As of 2001, about 400 of those are preserved in Mecklenburg-Vorpommern, 55 of which are located on the isle of Rügen. Initially their number had been much larger, but many were destroyed when their boulders were used for church, housing and street construction since the Middle Ages. In the 20th century, local teacher Friedrich-Wilhelm Furthmann and his wife preserved the dolmens in the Lancken-Granitz and Burtevitz area, before they were excavated by archaeologist Ewald Schuldt in 1969 and immediately thereafter restored for touristic use. This was part of a series of 106 excavations conducted by Schuldt's team on megalith sites in present-day Mecklenburg-Vorpommern between 1964 and 1972.
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.
