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.References:
Bouillon Castle was mentioned first in 988, but there has been a castle on the same site for a much longer time. The castle is situated on a rocky spur of land within a sharp bend of the Semois River.
In 1082, Bouillon Castle was inherited by Godfrey of Bouillon, who sold it to Otbert, Bishop of Liège in order to finance the First Crusade. The castle was later fitted for heavy artillery by Vauban, Louis XIV's military architect in the late 17th century.
The castle is entered over three drawbridges. The main courtyard then leads to the ducal palace with its 13th century Salle Godefroy de Bouillon. From there visitors climb up to the top of the 16th century Tour d’Autriche for a breathtaking panorama of the town and river, before they way back via the torture chamber, citerns and dungeons, and past the 65m deep well Shaft.
