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. The "Light Mound" will not be complete until it is clad with heather, a process that will take years. At the same time, sheep are to graze on it - they eat everything but heather.
The pulsating of the light is best seen at night - the light intensity and rhytm being determined by the intensity of the traffic on the West Coast road.
