After a long permit procedure, the advertising mast at Van der Valk in Oostzaan was completed in August 2017. The advertising mast with a height of 38 meters was realized by VDL and has 2 LED screens of 78m² on both sides. On this mast, which is located next to the hotel, own and other advertising messages are shown. Both LED screens come from the Eco line, with lower energy consumption.
