The great dolmen or grand dolmen〔Bakker, JA (1992). ''The Dutch Hunebedden'', University of Michigan. 〕 ((ドイツ語:Großdolmen), (デンマーク語:Stordysse)) is a type of megalithic site of the Funnelbeaker culture (TBK) that occurs in Nordic megalith architecture, primarily in the east of what is now German Mecklenburg-Vorpommern, and which has two different types of entrance. Neolithic monuments are features of the culture and ideology of Neolithic communities. Their evolution and function act as indicators of social development.〔J. Müller In: Varia neolithica VI 2009 p. 15〕 The type of site, called ''Stordysse'' in Danish, does not follow the criteria listed below. In Germany, dolmens with three or more capstones are described as great dolmens and are divided into: * Great dolmens with an antechamber (''Vorraum'') * Great dolmens with a porch (''Windfang'') The porch dolmen is mainly found on the island of Rügen and on the mainland opposite the island. The antechamber dolmen is found southeast of that, between Demmin and the island of Usedom. Several variant, but very rare examples recall the extended or polygonal dolmen types. In Mecklenburg there are 146 great dolmens, of which Ewald Schuldt has investigated 44. There are also two great dolmens in Schleswig-Holstein (Wees, Flensburg county and in Nebel auf Amrum), several in western Lower Saxony, but quite a few in Saxony-Anhalt (e.g. Lüdelsen 3). Since the width of northern megalith sites is limited due to the source material used, the main design aim of their longitudinal extension was an effort to increase the size of the chambers. Great dolmens reach an average interior size of 14 cubic metres, a scale only otherwise matched by that of the gallery and passage grave. Great dolmens have up to five capstones lying on eight to twelve supporting stones. Several great dolmens were extended using wide piers (''Zwischenmauerwerk''), on which, in certain cases, even capstones may have been placed. Like passage graves, great dolmens are a type of layout, in which the centre capstones were sometimes placed in a bay configuration (''Jochbauweise'', see picture). Whilst, initially, the roof was only built in such a way that its structural stability was based on a three-point support, in the later bay designs, a capstone could be supported on just two uprights (forming a single bay), the three stones being built as one unit, like a trilithon. The 44 great dolmens that have been investigated were found in various configurations. Five were surrounded by rectangular and 8 by trapezoidal frames of standing stones; 4 were buried under circular mounds, but the majority, 26, were under mounds covered by boulders. In one case, the type of mound was not known because it had been removed. The trapezoidally-framed dolmens (e.g. Dwasieden, Lancken-Granitz I, Kruckow, Nadelitz, Pöglitz, Poggedorf Forest) have guardian stones, sometimes at both ends. The great dolmen of Gaarzerhof, which initially lay within a very short rectangular frame, was eventually covered with a circular mound. == See also == * Nordic megalith architecture * Great dolmen of Damerow * Great dolmen of Dwasieden * Great dolmen of Sassen * Great dolmen of Serrahn 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「great dolmen」の詳細全文を読む スポンサード リンク
