The Charente region, the grapes of which furnish brandy, as do those of Armagnac (department of Gers).
Armagnac is a region of hills ranging to a height of 1000 ft., watered by the river Gers and other rivers which descend fanwise from the plateau of Lannemezan.
In 1789 Armagnac was a province forming part of the Gouvernement-general of Guienne and Gascony; it was divided into two parts, High or White Armagnac, with Auch for capital, and Low or Black Armagnac. At the Revolution the whole of the original Armagnac was included in the department of Gers.
Auch is built on the summit and sides of a hill at the foot of which flow the yellow waters of the Gers.
Three bridges lead from the left to the right bank of the Gers, on which the suburb of Patte d'Oie is situated.
