The Basilica of Saint-Romain in Blaye was an important Merovingian basilica, the resting-place of Charibert II, a son of Clotaire II who was briefly king of Aquitaine from 629 to his death in 632, and of his son. According to the 12th-century Chanson de Roland contained the body and relics of the Carolingian folk-hero Roland, who was a seigneur of Blaye in the eighth century.
The nominal patron of the basilica, belonging to the Canons Regular of Saint Augustine, remained the local 4th-century martyr Saint Romanus of Blaye; here the pilgrims bound for Santiago de Compostela paused before taking to boats to cross to Bordeaux.
In 848, the fort and its surrounding habitations were laid waste by the Viking chief Hasting.
Some vestiges of the structure remain within the Vauban fortress at Blaye, which formed part of the traditional defenses of the Gironde estuary.

Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
