This big grey sloping building is Amager Bakke, also called CopenHill. CopenHill links a new waste incineration plant from March 2017, which efficiently and safely converts residual waste into district heating and electricity, with an artificial ski slope, walking trails and many more outdoor activities on its roof, which opened in October 2019. In addition, the world's tallest climbing wall at 85 meters is mounted on one side of the incineration plant and it has 10 different routes to the top (you have to be an experienced climber to try it out).
You can visit both the incineration plant and the rooftop. Walking on the roof is free but skiing (NOT including rent of equipment) is about €27 per hour.
There's also a rooftop bar where event are held such as concerts and treasure hunts.
