HISTORY OF THE COUNTRY

214 million years ago, in the Jurassic age (of the great sauriens) the fall of a heavenly body, 4 kms west of Rochechouart, transformed the surface of our earth. Since then, a million and a half centuries have eroded the crater formed by the meteorite's impact.

The crater ( ASTROBLEME) with a diameter of 20 km, is almost completely eroded and can no longer be distinguished. The meteorite, with a diameter of 1 km 5 weighinh 6000 million tons impacted at 20 km/second, giving off energy equivalent to (300 000 megatons of TNT (14 000 000 times more powerful than Hiroshima). The shockwave (42000 km/s) transformed the underlying rocks to from the "BRECHE" rocks which intrigued leading geologists for a long time.
These "BRECHE" rocks resemble those taken from the moon's surface.
The certain advantage of this "tiny addition" to the earth was that the transformed rocks, the "BRECHES", were used as buiding materials in almost all the ancient constructions.

I had to note: I was not aware that there was another church with the same characteristics as the one in the picture. So you definitely learned me something new today.
