A Bastide is a type of fortified town that originated in France during the 13th century. These towns were designed for defense and often featured a grid layout, with streets intersecting at right angles. Bastides were typically built in areas that were strategically important for trade or military purposes, providing safety for inhabitants and travelers. The architecture of a bastide usually includes a central square, surrounded by houses and shops, with walls and towers for protection. Many bastides, such as those in the regions of Aquitaine and Languedoc, still exist today and are known for their historical significance and charming medieval character.
