Nördlingen is a town in the Donau-Ries district, in Swabia, Bavaria, Germany. It was built in a 15 million year old & 25 km diameter wide impact crater - the Nördlinger Ries - of a meteorite which hit with an estimated speed of 70,000 km/h, and left the area riddled with an estimated 72,000 tons of micro-diamonds.
