What city is built in a meteor crater?
Nördlingen
Nördlingen is literally made of diamonds—millions of microscopic diamonds to be exact—with the town itself constructed within an ancient impact crater. The 25 kilometer-wide Reis crater in which the town sits was formed approximately 15 million years ago after an asteroid collided with this region of Bavaria.
