The taller of Woudsend's two surviving windmills, 't Lam ("The Lamb") stands at the western end of the village on the north bank of the Ee. It is a thatched smock mill, the body octagonal and tapering, with a cap that rotates on a wooden ring so the sails can face the wind. Built in 1690, it is one of the few wind-powered sawmills still in operating order in the country.
The mill is open to visitors on Saturdays from spring to autumn (volunteer-run, free or by donation). When the wind cooperates, the sails turn and the long horizontal saws work timber on the open ground floor; on still days you can still climb up through the working floors and out onto the stage. The view across to the second mill, De Jager, on the other side of the bridge is one of the iconic images of inland Friesland.
