Tintagel Castle is a medieval fortification located on the peninsula of Tintagel Island adjacent to the village of Tintagel, North Cornwall. The site was possibly occupied in the Romano-British period, as an array of artefacts dating from this period have been found on the peninsula, but as yet no Roman-era structure has been proven to have existed there. It was settled during the early medieval period, when it was probably one of the seasonal residences of the regional king of Dumnonia. A castle was built on the site by Richard, 1st Earl of Cornwall in the 13th century, during the High Middle Ages. It later fell into disrepair and ruin.
In the 1930s, excavations revealed significant traces of a much earlier high status settlement, which had trading links with the Mediterranean world during the Late Roman period. Later digs uncovered the outlines of a palace from the 5th or early 6th century (the early medieval period), with evidence of writing and of articles brought in from Spain and from the eastern end of the Mediterranean Sea.
The castle has a long association with legends related to King Arthur. This was first recorded in the 12th century when Geoffrey of Monmouth described Tintagel as the place of Arthur's conception in his mythological account of British history, Historia Regum Britanniae. Geoffrey told the story that Arthur's father, King Uther Pendragon, was disguised by Merlin's sorcery to look like Gorlois, Duke of Cornwall, the husband of Igraine, Arthur's mother.
The castle was built on the site by Earl Richard in 1233 to establish a connection with the Arthurian legends that were associated by Geoffrey of Monmouth with the area and because it was seen as the traditional place for Cornish kings.
Tintagel Castle has been a tourist destination since the mid-19th century. Owned by William, Prince of Wales as part of the landholdings of the Duchy of Cornwall, the site is managed by English Heritage.
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.
