When you see the famous prehistoric paintings at the Lascaux Cave in Dordogne, you must purchase your tickets in the village of Montignac. (Ticket purchase is not available on-site.) You won’t feel inconvenienced by this because Montignac is beautiful and worth a stop to explore its two different areas located on both sides of the Vézère River. On the right bank, there’s a feudal town with medieval narrow streets with architecture from the 14th, 15th and 16th centuries. On the left bank, the suburb with a convent and priory is an indication that Montignac used to be a harbor town, a place of artisans, crafts, arts and other sell-able goods.
