Restormel Castle lies by the River Fowey near Lostwithiel in Cornwall. It is one of the four chief Norman castles of Cornwall, the others being Launceston, Tintagel and Trematon. The castle is notable for its perfectly circular design. It is an unusually well-preserved example of a circular shell keep, a rare type of fortification built during a short period in the 12th and early 13th centuries.
Although once a luxurious residence of the Earl of Cornwall, the castle was all but ruined by the 16th century. It was briefly reoccupied and fought over during the English Civil War but was subsequently abandoned. It is now in the care of English Heritage and open to the public.
Today the castle commands fantastic views across the valley of the river Fowey and is a favourite picnic spot – with beautiful spring flowers, and plants all year round.
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.
