The Château de Florac was originally built in the 13th century and then rebuilt in the 17th century. It originally belonged to the Barony of Anduze and passed through a number of feudal families. The castle was entirely rebuilt in 1652 after the Wars of Religion. During the French Revolution, the castle was turned into a 'salt loft' for storing salt. It was then used as a prison in the 19th century.
Since 1976, the castle has been the headquarters of the Cévennes National Park, who restored it. The ground and first floors house an exhibition on the National Park (landscape, flora, fauna and activities connected with the park). The information centre has details of hiking, guided tours, accommodation and écomusées (open-air museums) in the park.
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.
