The Château de Careil is a fortified house constructed from the end of the 14th century and enlarged in the 15th and 16th centuries. The manor had originally a defensive function, as witnessed by the crenellated curtain wall which still exists. Under the Reformation, it served as a place of worship for the protestants established in the Guérande peninsula. For this reason, it was attacked and pillaged on 11 May 1589 by the Catholic League. In 1699, some time after the Revocation of the Edict of Nantes, the manor was siezed and sold to a Catholic family. After becoming a restaurant in 1924, the site is currently a visitors' centre. A third wing of the building no longer exists; it was destroyed in an accidental fire in the 18th 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.
