Wormerveer is a town in the Dutch province of North Holland. It is a part of the municipality of Zaanstad, and lies about 13 km northwest of Amsterdam. Wormerveer developed in the 15th century on the west bank of the Zaan river. It started to industrialise with windmills in the 17th century, however none of the windmills exist any more. The Dutch Reformed church was built in 1639 to replace the medieval church which was destroyed in 1574 by Spanish troops.
