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:The ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
