450 years of Leeghwater 1575-2025

Jan Adriaensz. Leeghwater is a household name in the Netherlands. Almost everyone knows the name of this hydraulic engineer and mill builder, who came into the world in the North Holland village of De Rijp in 1575. In 2025, the year of his birth will be exactly 450 years behind us. This will be commemorated in the 'Land of Leeghwater' between Alkmaar and Purmerend with special theme days, an exhibition in the Rijper Museum, a Leeghwater glossy and, last but not least, a 'Leeghwater 450' stamp (see Leeghwater 450 and Leeghwater 450 years).
