The International Wind- and Watermill Museum, at Gifhorn in the German state of Lower Saxony, is the only one of its kind in Europe. On the museum's open-air site, which covers an area of around 16 hectares, there are currently 16 mills from 12 different countries. The mills are either original or faithful reproductions and are set in landscapes typical of their origins. Right across the site are historic artefacts associated with mills and the milling industry. The museum site is easily accessed by road; nearby is the intersection between the B 4 and B 188 federal highways. The museum is station 65 on the Lower Saxon Mill Road.

Gifhorn is a town and capital of the district of Gifhorn in the east of Lower Saxony, Germany.
