Hornsluis at Schardam
The Hornsluis is a Water barrier and culvert and is a National Monument. Schardam's first Hornsluis was built in 1607 at the expense of the investors who had the Beemster reclaimed. Just over a hundred
years later, in 1735, the wooden lock was replaced by a lock made of stone.
This renovation was much needed, as the wooden lock was badly affected by pile worm and therefore in danger of collapsing. To commemorate this renovation, gable stones were set into the walls of the 'new' lock. One shows the Beemster coat of arms and the other a cartouche with the coats of arms of the dike grave and heemraden of the Beemster.
