Early Neolithic communities occupying much of Switzerland during the 4th millennium bc, named after the lake village of Cortaillod beside Lake Neuchâtel. Many settlements of the Cortaillod Culture were situated beside lakes or on the edge of wetland, with the result that remains are often well preserved. The houses were timber‐framed with clay walls and thatched roofs. Their material culture included numerous birch‐bark utensils and containers, fibre nets and ropes, and dark burnished round‐based pottery. The subsistence base focused on mixed farming supplemented by hunting, fishing, and collecting wild foodstuffs including fruits and nuts. The Cortaillod Culture was succeeded by the Pfyn Culture in eastern Switzerland and the Horgen Culture in western Switzerland.
