Wetzikon-Robenhausen, Archaeological excavation site in Wetzikon, Switzerland

Wetzikon-Robenhausen is a prehistoric pile-dwelling settlement on the southern shore of Pfäffikersee in the Robenhausen wetland, covering about 10 hectares with a 20-hectare buffer zone. Excavations found rectangular huts of roughly 6–7 m by 40 m², raised on oak and softwood piles 12–18 cm thick, with clay-and-straw walls and moss-lined sleeping areas.

Excavations began in the mid-1800s and revealed Neolithic artifacts including tools and household items. These discoveries represent some of the earliest known settlements in the region and provide evidence of how people lived in prehistoric times.

Jakob Messikommer, who found the site in 1856–1858, uncovered woven fabrics, braids, a raffia mat and parts of a Neolithic loom, evidence of textile work at Robenhausen. He also identified 58 animal species among the organic finds and reported signs of butter production. A memorial stone and the Messikomer Eich oak in the Robenhausen reed commemorate him.
