Les Bastides are fortified towns that originated in the 13th century in the region of Occitanie, France. They were designed to promote trade and agriculture while providing protection against invasions. Characterized by their grid-like street layouts, these towns often feature central squares and are surrounded by walls. Many bastides were built during the Hundred Years' War to strengthen territorial control. Today, they are known for their historical architecture and charming landscapes, attracting visitors interested in medieval history and rural tourism. Examples include Bastide de Monflanquin and Bastide de Villeneuve-sur-Lot.
