Cardigan Castle overlooks the River Teifi in Cardigan, Wales. The first motte-and-bailey castle (ca. 1093) was built a mile away from the present site, probably about the time of the founding of the town by Roger de Montgomery, a Norman baron.
The castle was later recaptured by the Normans, and was held for Earl Roger of Hertford. In 1166 it was captured by Rhys ap Gruffydd, who rebuilt it in stone in 1171. In 1176 the first recorded eisteddfod was held at the castle.
Llywelyn the Great captured it in 1215 and at the parliament held at Aberdyfi in 1216 made it over to the sons of Gruffydd ap Rhys of Deheubarth, but in 1223 William Marshall the Younger recaptured it. In 1231 the castle was again captured for Llywelyn by Rhys Gryg and his allies. Llywelyn held it until his death in 1240. On Llywelyn's death it fell back into Norman hands, and in 1244 Earl Gilbert of Pembroke rebuilt it with town walls for added protection. It is the remains of this building that still stands overlooking the river.
Cardigan Castle was badly damaged during the English Civil War in Wales and until the 18th century it was only used as a prison. Sometime between 1805 and 1808 the castle owner, John Bowen, arranged the construction of Castle Green House within the castle walls. The front range was added in 1827.
Renovation work continued for some years after its purchase by the Council, and the castle was opened to the public in 2015. The new facilities include bed-and-breakfast and self-catering accommodation, a heritage centre with education facilities, a restaurant, an events and open-air concert area, and rooms for hire for classes.
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.
