Obfelden

Politically, Obfelden is the youngest municipality in Affoltern, though settlements in the area date back to the Alemannic-Franconian period in the 5th century AD. Early activity coalesced around five hamlets: Bickwil , Oberlunnern and Unterlunnern , Wolsen , and Toussen . These five hamlets were known collectively as being ob dem Feld from neighbouring Ottenbach; most fell under the jurisdiction of Maschwanden, although Toussen and part of Unterlunnern came under the Zürich Freiamt. Both of these areas were merged into Knonau in the sixteenth century, when the hamlets of Obfelden became a part of the nearby parish of Ottenbach.
In the nineteenth century, local authorities began to take steps toward creating their own separate community, and an independent ecclesiastical and municipal entity was formally created in 1847 under a new village church completed the following year. The original separate hamlet councils were officially dissolved in 1877. The town's coat of arms commemorates this history, with five ears of wheat symbolising the five hamlets, held together by a band representing their union to the new church.
