As a tribute to the beautiful in the energy of light and as a reference to the Danish Niels Bohr’s atomic model and the principle of light transmission, the green laser – one of the most distilled forms of light – connects the heart of Tivoli with the spire at Nikolaj Kunsthal. It stretches one kilometer and reaches 65 meters in the air between the two extremes on the route during the Copenhagen Light Festival.

Every day at sunset the beam turns on as an extension of winter’s sparse sunbeams and works very concrete as a indicator of what time the sun has gone below the horizon.
