Wip Mill at Hazerswoude

The Wip Mill at Hazerswoude is a rare hollow-post wip mill still actively pumping water in South Holland's polder landscape, a function that is 40% more efficient than the typical drainage mill of its era. This 16th-century marvel processes up to 1,200 cubic meters of water per hour, outperforming #5 De Otter's sawing capacity in sheer hydraulic power. Its compact wooden structure, only 8 meters tall, defies expectations by handling flood control without modern pumps, making it a vital piece of living water management heritage.
