Château de Lanquais stands on the southern bank of the Dordogne River near Bergerac, showcasing a striking blend of medieval fortification and Renaissance elegance. Dating from the 12th century with significant 14th and 16th century additions, the château features Italian Renaissance architecture reminiscent of the Louvre, earning it the epithet 'the unfinished Louvre of the Périgord.' The castle is open to visitors from April through October, excluding Tuesdays, and welcomes picnicking on its grounds. Its historical significance includes connections to Isabelle de Limeuil, born within its walls and later appointed to the court of Catherine de Medici as one of the legendary 'flying squadron' ladies-in-waiting.
