Dutch Windmill Society

Vereniging De Hollandsche Molen is a Dutch organization founded in 1923 to preserve windmills in the Netherlands, to document them, and to restore them. Financial support comes from members and from grants by organizations such as the BankGiro Loterij. Their website provides access to a database which documents some 1400 mills in the Netherlands; "Het Nederlands Molenbestand" is authoritative on the topic. The organization is often given credit for organizing a powerful and effective lobby aimed at procuring money from Dutch government institutions to fund restoration projects.
