The Windmotor Spanga is a modern watermill located on Spangahoekweg in the town of Spanga. The mill is a fairly small U.S. Wind Engine, with a flight of just 4.5 metres. The U.S. Wind Engine design was very popular in the Friesland region during the first half of the 20th century, although many of the mills using this design have since been decommissioned. The Windmotor Spangahoekweg is not open to the public.
