The map of national monumental locks and dams shows water-related works of art that are protected as a national monument. A point location can be a single lock or stow, or a lock and stow complex. Not all artworks are still in use as quay.
The map also contains many (historical) locks and dams that are part of a defensive work, such as the New Dutch Water Line.
The map is based on the Monuments Register, which is managed by the National Cultural Heritage Office. From the map you can click to the Monuments Register where you can find more information about the monument.
