Zaans Museum is a museum in Zaandam, Netherlands, founded in 1994. It is housed in a contemporary building designed by architects Cor van Hillo and Monique Verschaeren, right across from the historic windmills and houses of the Zaanse Schans, an open-air museum. The museum covers 16,500 m and contains items showcasing the past of the area of the Zaan, and the wealth created by the early industrial activity on the river. The building was expanded in March 2009 with a new pavilion, to house the corporate collection of the Verkade family.
