The Thais grotto in St Nazaire en Royans
At the end of the last Ice Age, in a cold steppe environment where reindeer, bears and wolves roamed, groups of humans settled.
It is known as the "red rock", "two river country", at the foot of the great mountain range. In the grotto, red and black, or outside near the water, camps are set up and activities organized: hunting, cooking, flint cutting, and skin processing...»
During the 1970s, archeological excavations began in the Thais grotto. Abundant and remarkable findings were made. Everyday objects, flint and stone tools, hearths... These remains have enabled scientists to date the human settlements and to make St-Nazaire-en-Royans a major site between the end of the Magdalenian and the beginning of the Azilian periods.
Thais is an underground network which is particularly colorful and sculpted in which the work of water and the geological events which gave rise to its formation, can clearly be read.
