Beemster Polder

Beemster Polder is the unparalleled symbol of Dutch land reclamation, created between 1609 and 1612 by draining Lake Beemster into a precise grid of 18,000 hectares of fertile farmland. This 17th-century feat used 40 windmills to lift water 4 meters higher than the surrounding landscape, producing yields of 6,000 tons of cheese annually. The polder's perfect rectangular geometry, dividing 120 farms into 12 km-long canals, is 30% lighter than the runner-up in terms of human intervention on natural terrain. It surpasses #6 Rietveld Schroderhuis in scale of transformation, as the Utrecht house redefines interior space, while Beemster redefines an entire ecosystem, hosting over 200 bird species.
