The Earth is filled with bewildering places and structures and in most cases they are either built naturally by forces within the Earth or by humans. However, there is one place on Earth that ranks among the most unique places on the planet, yet the credit does not go either to humans or the planet itself. Nordlingen is a small town in Bavaria, Germany which may not appear out-of-the-ordinary, but it is much frequented by NASA and ESA astronomers. Why? It's because the entire town is built on an asteroid crash site. Yes, as an asteroid strike actually happened there! But that's not all. Surprisingly, the stones used to construct most of the structures in the town are filled with diamonds, thanks to the asteroid.
It turns out that 15 million years ago, a massive one-kilometer-wide asteroid struck the very same land on which the town is built today. The asteroid struck at a speed of 70000 kilometers per hour and created a 25 kilometers wide crater on Earth which is today known as Nordlinger Ries. Interestingly, no one knew about this crater till very recently and the popular notion was that the town was built upon an extinct volcano.
The earliest records for the construction of the town go as far back as the 9th century. And based on the record, the settlers were not aware that the land they were building houses upon was an asteroid crash site. In fact, even the school books in the 20th century mentioned that the town had a unique shape due to it being built on an extinct volcano.
It was not till the 1960s when geologists from the USA visited the town and found out that the shape of the ground did not resemble that of a volcano but something that was shaped from above. Inspecting the area, it did not take scientists long to
