Nördlingen is a town in the Donau-Ries district, in Swabia, Bavaria, Germany, with a population of approximately 19,190. It is located approximately 115 km east of Stuttgart, and 145 km northwest of Munich. 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.
Nördlingen was first mentioned in recorded history in 898, and in 1998 the town celebrated its 1100th anniversary. The town was the location of two battles during the Thirty Years' War, which took place between 1618 and 1648. Today it is one of only three towns in Germany that still have completely intact city walls, the other two being Rothenburg ob der Tauber and Dinkelsbühl.
Another attraction in the town is Saint George's Church's 90-metre steeple, called "Daniel", which is made of a suevite impact breccia that contains shocked quartz. Other notable buildings are the town hall, St. Salvator church and the Spital, a former medieval hospital. The Ries crater museum is located in the well-preserved medieval tanners' quarter.
