Dol Cathedral (Cathédrale Saint-Samson de Dol) was formerly the seat of the Archbishop of Dol, one of the nine ancient bishoprics of Brittany. The archbishopric was suppressed during the French Revolution and abolished by the Concordat of 1801, when it was merged into the dioceses of Rennes and St. Brieuc.
The building is notable for its eclectic mix of styles and idiosyncrasies, such as the incomplete north tower on the main west-facing entrance. The tower was begun in 1520 but never finished due to lack of funds. A local myth has it that the top was knocked off by the devil, who threw the nearby Dol menhir at the building, which was buried in the ground in consequence.
The south facade contains a small 13th-century porch, known as the Bishop's porch. This was supplemented by a much grander porch in the 15th century. The latter was decorated with biblical relief carvings by the sculptor Jean Boucher at the end of the 19th century.

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.
