In the middle of the city of Copenhagen there is a place where you can see the whole city from a rooftop. Inside the construction there is a 25 meter drop exactly at the point zero of the country. There was a point in time when they wanted to measure the whole of Denmark as all maps where not accurate enough; so they chose this zero point to base their measurements from.
There is also a tale about a boy who fell through a gap and dropped the whole 25 meters down only losing a few teeth in the process.
Standing in the middle of a glass platform of this drop was definitely something.
