The first written record of the Hasli mill goes as far back as 1448. In 1653 it burned down to the ground. In 1662 the newly rebuilt mill was purchased by the parish of Müllheim-Wigoltingen. The mill was leased out and the local farmers were obliged to have their grain milled at the Hasli mill. Until 1861, the mill was run with the hydraulic power provided by the Kemmenbach stream. Though later it was able to benefit from power provided by the canal of the river Thur which was branched off at Weinfelden and rejoined the river at Pfyn. In 1971, due to a legal dispute, the Thur canal was closed and filled in.
