Dolmen: Neolithic Megalithic Tomb Structures

Characteristics and parts

Most dolmens share a simple architectural vocabulary: upright stones (orthostats) support a large flat capstone, creating a chamber. Typical components include:

• Upright megaliths forming walls or supports.
• A horizontal capstone or tablestone that covers the chamber.
• Occasionally a short entrance or threshold; some were extended by cairns or earthen mounds.

When intact, the stone framework was frequently enclosed beneath a covering of earth or rubble to produce a barrow or cairn, though such coverings often erode over millennia.

History and geographic distribution

Dolmens appear in many regions of Europe, the Near East, and parts of Asia and North Africa. They are especially common in Atlantic Europe but also occur in Korea, India and the Caucasus. Their emergence in the Neolithic reflects changing funerary practices as farming communities became more settled.

Uses and cultural significance

Archaeologists interpret dolmens primarily as communal burial or commemorative sites. Excavations commonly recover human remains, grave goods and pottery, indicating repeated use and social importance. Beyond burial, dolmens likely had symbolic and territorial roles within prehistoric landscapes.

Study, preservation and differences

Research combines excavation, radiocarbon dating and landscape survey to place dolmens in time and context. Many have been altered, reused or damaged by later activity; others remain impressive examples of prehistoric engineering. Dolmens differ from more complex passage graves and chambered cairns by their relatively simple single‑chamber form.
