CopenHill (Amager Bakke)

Impressive architecture: waste burning plant with public access to the slanted roof where you can ski all year round. Also a public garden suitable for hill training or just enjoying the view.

For those into climbing there is an artifical wall with 4 pitches on the side, but you can also hike up the 'hill'.

A multifunctional building. On the one hand, a mildly stinking waste incineration plant - and no matter what the Denmark advertising claims: it smells.On the other side, bouldering poles and downhill skiing for newbies and flatlanders.And at the very top a viewing platform and quite obviously a company outing destination with the possibility of getting completely drunk. The gentlemen that I found there, at least, had a pretty good time around half past one. So much so that you could start a conversation with them even though they were Danish.
