A dolmen, also known as a portal tomb, portal grave or quoit, is a type of single-chamber megalithic tomb, usually consisting of two or more upright stones supporting a large flat horizontal capstone (table), although there are also more complex variants. Most date from the early Neolithic period (4000 to 3000 BC). Dolmens were typically covered with earth or smaller stones to form a barrow. In many instances, that covering has weathered away, leaving only the stone "skeleton" of the burial mound intact.It remains unclear when, why, and by whom the earliest dolmens were made. The oldest known dolmens are in Western Europe, where they were set in place around 7000 years ago. Archaeologists still do not know who erected these dolmens, which makes it difficult to know why they did it. They are generally all regarded as tombs or burial chambers, despite the absence of clear evidence for this. Human remains, sometimes accompanied by artifacts, have been found in or close to the dolmens which could be scientifically dated. However, it has been impossible to prove that these archaeological remains date from the time when the stones were originally set in place.

The Altmark (English: Old March) is a historic region in Germany, comprising the northern third of Saxony-Anhalt. As the initial territory of the Brandenburg margraves, it is sometimes referred to as the "Cradle of Prussia", as by Otto von Bismarck, a native from Schönhausen near Stendal. The Altmark is located west of the Elbe river between the cities of Hamburg and Magdeburg, mostly included in the present-day districts of Altmarkkreis Salzwedel and Stendal. In the west, the Drawehn hill range and the Drömling depression separate it from the Lüneburg Heath in Lower Saxony; the Altmark also borders the Wendland region in the north and the Magdeburg Börde in the south. Adjacent east of the Elbe is the historical Prignitz region.
