Megalith - European Megaliths

European Megaliths

The most common type of megalithic construction in Europe is the portal tomb – a chamber consisting of upright stones (orthostats) with one or more large flat capstones forming a roof. Many of these, though by no means all, contain human remains, but it is debatable whether use as burial sites was their primary function. Though generally known as dolmens, the correct term accepted by archaeologists is portal tomb. However many local names exist, such as anta in Galicia and Portugal, stazzone in Sardinia, hunebed in the Netherlands, Hünengrab in Germany, dysse in Denmark, and cromlech in Wales. It is assumed that most portal tombs were originally covered by earthen mounds.

The second-most-common tomb type is the passage grave. It normally consists of a square, circular, or cruciform chamber with a slabbed or corbelled roof, accessed by a long, straight passageway, with the whole structure covered by a circular mound of earth. Sometimes it is also surrounded by an external stone kerb. Prominent examples include the sites of Brú na Bóinne and Carrowmore in Ireland, Maes Howe in Orkney, and Gavrinis in France.

The third tomb type is a diverse group known as gallery graves. These are axially arranged chambers placed under elongated mounds. The Irish court tombs, British long barrows, and German Steinkisten belong to this group.

Another type of megalithic monument is the single standing stone, or menhir. Some of these are thought to have an astronomical function as a marker or foresight, and, in some areas, long and complex alignments of such stones exist, for example, at Carnac in Brittany.

In parts of Britain and Ireland the best-known type of megalithic construction is the stone circle, of which examples include Stonehenge, Avebury, Ring of Brodgar, and Beltany. These, too, display evidence of astronomical alignments, both solar and lunar. Stonehenge, for example, is famous for its solstice alignment. Examples of stone circles are also found in the rest of Europe. They are assumed to be of later date than the tombs, straddling the Neolithic and the Bronze Ages.
