The keep of Crupet Castle was built in the 13th century and originally consisted of a square tower surrounded by a moat. The entrance was probably protected by a drawbridge and portcullis. In the 16th century, the keep was converted to a manor house. A corner tower was added, the windows were enlarged, and the timber top floor and roof were built. The drawbridge was probably also replaced at this time. The keep is not open for visits, but is highly visible from the surrounding roads.
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.
