A map of Sloten - one of the Eleven Frisian towns - from 1523 shows a windmill in its present location for the first time. Windmill De Kaai was built in 1755 and is the successor to the earlier standerd mill that stood on this spot. For many years it was known as De Korenmolen (The Corn Mill). It was given its ‘new’ name in 2006, derived from its position by the Lemster Poort - one of the two water gates in Sloten; where it stands on a bastion of the city wall. De Kaai is a smock mill on a brick base with a thatched smock and cap. Its stage is 3.40 meters above ground level. The mill is winded by tailpole and winch. The sails have a span of 18.10 meters. De Kaai still grinds wheat into flour in the traditional and authentic manner. On Saturdays, the mill is open for viewing and flour sales. The mill is listed as a Dutch national heritage site.

Woldzigt (meaning “view of the woods”) is an octagonal smock mill. It is a three-storey mill on a four-storey brick base. The stage is at third-floor level, 10 meters above ground level. The smock and cap are thatched. It is a quite unique windmill, as it has two buildings on the side; one was used to house the miller and the other as some kind of factory housing. The mill is dating back to 1852, when it was built as a combined corn and oil mill. The oil mill was used to crush linseed and rapeseed to produce oil. The season for oil milling ran from September until May. Throughout the year the mill also functioned as a corn mill. In 1902 the mill was sold and a petrol engine was installed as auxiliary power. Four years later the petrol engine was replaced by a steam engine. In 1941, the mill ceased to produce oil. Corn milling ended in 1951. In 1970 the mill was sold to the municipality of Roden. The mill was completely restored in 1976. In 2016 Woldzigt was transferred by the municipality to Het Drentse Landschap (a foundation aiming to preserve the landscape and cultural history of the province of Drenthe). The mill is managed by Stichting olie- en korenmolen Woldzigt (Oil and corn mill Woldzigt Society). The mill is entirely ready for operation. It is open for visitors, although with limited opening hours. The Dutch Grain Museum houses in a side wing of the mill.
