The Winding Chimney 

Carl Jacobsen wanted to show that a chimney for an industrial plant could be beautiful in its own right, so he brought in architect Vilhelm Dahlerup and master builder PS Beckmann. Their 56m tall winding chimney features motifs of Egyptian lotus flowers while, on the plinth, replicas of the Chimeras (Gargoyles) from Notre Dame in Paris look out over the city of Copenhagen.

This unique chimney is no longer in use, as it was replaced by a 100m tall chimney in 1980.
