The only functional windmill in Stockholms län

The Överby mill, located in Sollentuna kommun, near the border with Upplands Väsby kommun, is a windmill of the hättkvarn or holländare type, with a fixed foundation and a rotatable hat. The windmill is the only functional windmill in Stockholms län. Twice a year, at recurring mill days, grain is ground into flour.

Built around 1850 and possibly having a predecessor from the 1700s, the mill is depicted on a map for the first time in 1810. The stones from the predecessor are displayed outside the mill. The mill likely served as a toll mill, grinding for the public for a fee, with an arrender serving as the miller.
