Before long, the historic tempered glass plaque had been lost. An employee of a waste station is presented with the plaque, but fortunately immediately sees that he has something special in his hands. Because the plaque mentions a steam pumping station, he contacts Boesjes-Beljon. For many years she was director of the Woudagemaal foundation, the largest working steam pumping station in the world.
Woerdense plaque turns up 100 years later in Friesland
