Monument to Jan Adriaansz Leeghwater
Jan Adriaansz Leeghwater was born in De Rijp in 1575. He was a mill builder and hydraulic engineer and helped reclaim several large lakes in North Holland, including the Beemster (1612), Purmer (1622) and the Wormer (1626).
In the Purmer, it is commemorated with this plaque that forms part of a memorial bench placed at the Westerweg-Purmerenderweg intersection in 1922, when the Purmer was 300 years old.
