Hawarden Old Castle origins are indeterminate and the oldest fortifications on this site may date back to the Iron Age, later being used as a Norman Motte-and-bailey castle which was reportedly destroyed and replaced in a short period during the 13th century.
The castle played an important role during the Welsh struggle for independence in the 13th century. At Easter 1282, Dafydd ap Gruffudd attacked Hawarden Castle, thereby starting the final Welsh conflict with Norman England, in the course of which Welsh independence was lost. King Edward I's sense of outrage was such that he designed a punishment for Dafydd harsher than any previous form of capital punishment; Dafydd was hanged, drawn, and quartered in Shrewsbury in October 1283.
In 1294 the castle was captured during the revolt of Madog ap Llywelyn.
After the English Civil War in the 17th century the castle was slighted on the orders of Oliver Cromwell. Its ruins are on the New Hawarden Castle estate and are open to the public on some Sundays, typically the second and fourth Sundays in summertime.
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.
