Living in the Dordogne offers rich and varied experiences many of which are centred on its ancient villages and towns. The Dordogne region is famous for its historic fortified towns, known as bastides. They were mostly built during the reigns of King Henry III of England and his son Edward I. They were founded by the English kings and by local feudal landlords such as Raymond, Count of Toulouse, as part of the continual challenges to the authority of the descendants of Henry II, following his marriage in 1152 to Eleanor of Aquitaine. Aquitaine was at the time one of the wealthiest regions in Europe, and therefore a substantial asset to the kings of England for the next three hundred years until the end of the Hundred Years War in 1453.
