This is a panorama shot a few meter above the river Rupel on a structure to move small ships in and out of the water.
There used to be a lot of ship building in this area till the 1950 - 1960. At this time only one commercial company is left : http://www.spirit-yacht.com/ .
They are visible in the distance.
