Low Laender Sluys
The Lage Laender Sluys is one of the many locks formerly used for natural drainage of the peatlands near Assendelft and Krommenie.
The sluice opened at low tide and closed again at high tide. In winter, the locks were opened to allow water with silt to pass over the land, making the soil fertile. Now you have a beautiful view of Heemskerk's golf course.
Note: Go off the route for a bit after junction 38. Take the first road on the right (around the Kruitmagazijn near the Dam) and head towards Busch and Dam.
