Seine–Oise–Marne Culture
(SOM)
[CP].
Late Neolithic culture of the Paris Basin dating to the period 3400–2800 bc, characterized by a variety of tomb types including passage graves similar to those of Brittany, as well as local forms like simple stone-lined trench graves and underground gallery graves (allées couvertes), some with access through a circular ‘porthole’ in a blocking stone. Collective burial was practised. Grave goods include plain, flat-based, pots; leaf-shaped, tanged, and transverse arrowheads; a variety of stone ornamental pendants, amulets, and buttons; and occasional beads of copper.
