Therea re two castles in Erice, Pepoli Castle, with foundations dating from Arab times, and nearby Venus Castle, dating from the Norman period. Surrounded by a lush park, the hilltop castles alone are worth a stop in Erice, which offers charming old stone streets and several medieval churches. Pepoli Castle was at first a feudal stronghold, though Erice was eventually ceded to the Crown as a demesnial city. The view from the castle towers is stupendous. Though both castles have been modified somewhat over the centuries, they still have that distinctively medieval character one expects of such fortresses. Pepoli Castle is now a hotel.
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.
