Aveyron

Aveyron () is a French department found in the northeast of the Occitanie region of southern France and named after the Aveyron river. Its prefecture is Rodez.
History.
Aveyron is one of the 83 French departments made during the French revolution, on 4 March 1790. It was created with most of the territory of the old province of Rouergue; in fact, the present flag of the department was the flag of Rouergue.
The first known historical inhabitants of the region were the Rutenii tribe but, before them, the area was inhabited by people that built many prehistoric ruins including over 1,000 dolmens - more than any other department in France.
In 1808, the old canton of "Saint-Antonin-Noble-Val" was transferred from Aveyron to the new department of Tarn-et-Garonne.
