If you approach Esbjerg from the motorway, the first thing you will see is a colassal mound of earth with tiny cupolas of light spread out over it. This is Eva Koch and Steen Høyer's "Light Mound" (1997). It is one of Denmark's largest works of art, 180 metres in diameter, with an adjacent earthwork of 320 metres that is intersected by a road. https://www.visit-esbjerg.com/ln-int/light-mound-esbjerg-gdk1076853
