Château d'Harcourt, built between the 13th and 15th centuries, is the best-preserved castle in Chauvigny.
In the 13th century, a member of the noble Norman Harcourt family married the Viscountess of Châtellerault, who owned the estate. The castle remained in the Harcourt family for two centuries before being acquired by the Bishops of Poitiers in 1447.
The nearly rectangular fortress has high curtain walls, originally crenellated, with solid cylindrical towers. Measuring 38 by 25 meters, the enclosure dates from the 13th century. The entrance is protected by a gatehouse with a murder hole and a portcullis, but no drawbridge. The rectangular keep, with flat buttresses, was renovated in the 14th century. The ground floor contains a vaulted prison, still in use in the 19th century, with a door mechanism allowing one entrance to block another.
Attached to the keep, the heavily altered residence now hosts exhibition spaces.
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.
