Nördlingen is a town in the Donau-Ries district, in Swabia, Bavaria, Germany, with a population of approximately 19,190. It was built in an impact crater, and 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 1618–1648. Today it is one of only three towns in Germany that still has a completely intact city wall, the other two being Rothenburg ob der Tauber and Dinkelsbühl.
Another attraction in the town is Saint George's Church's 90 m 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 tanner's quarter.
