On the sluice complex stands a monument for the fallen Belgian front soldiers and their commander King Albert I. It was constructed on the initiative and with support of the National War Veterans’ Association in 1938. It was made out of clay dug from the banks of the IJzer river. Here and there are still traces of ordnance in the stones. On top of the monument you can enjoy a panoramic view of the IJzer plains and the city of Nieuwpoort.
The circular monument is 25 metres tall and is 30 metres in diameter. It has ten columns, built out of bricks from the Yser plain. A prominent circular beam caps the structure. On this beam, there is a walkway with orientation tables. On the central square of the monument, there is an equestrian statue of King Albert I, designed by Karel Aubroeck.
