It cuts the Dordogne in two from East to West following the course of the river Isle.
Centrally situated, it is a region of limestone plateaux rich in quarries which produced the noble white stonework of which the ancient buildings of Périgueux are made. We can also find wide valleys, rolling meadows and forests.
From Hautefort to Montpon including Périgueux, the region also features towns of interest such as Savignac-les-Eglises, Sorges (with its truffles), Saint-Astier, Neuvic and Mussidan.
