The New Driemanspolder Ondermolen is one of three mills that serve the 975 hectare New Driemanspolder. The mill was built in 1668, and was still in use as a primary drainage mill until 1951. The three mills were all built at the same height, which is quite unusual for a group of polder mills.The New Driemanspolder Ondermolen was bought by the province of South Holland in 1958. The mill is open to the public, and tours of the mill are available by appointment.
