Newcastle Castle was initially constructed as a ringwork 1106 by William de Londres, one of the legendary Twelve Knights of Glamorgan, as part of the Norman invasion of Wales. William de Londres was a knight loyal to the Norman baron Robert Fitzhamon and the Newcastle defences marked the most western extent of Fitzhamon's lordship.

The defences were strengthened either by William Fitz Robert, 2nd Earl of Gloucester, shortly before his death in 1183 or by Henry II who took over the lordship of Glamorgan on William's death. The additional works had the construction of a 2-m-thick curtain wall which surrounded a courtyard which was 40 m in length. The main reason behind these new defences was believed to be a response to the uprising in Glamorgan led by the Welsh Lord of Afan, Morgan ap Caradog. Henry died in 1189, and the ownership of Newcastle fell to Prince John, who that year handed the castle to Morgan ap Caradog. When Morgan died circa 1208, he was succeeded by his son Lleison. On Lleison's death, thought to be around 1214, the castle came into the ownership of Isabel, Countess of Gloucester, the first wife of King John. In 1217, the ownership changed again, staying briefly with the Anglo-Norman baron Gilbert Fitz Richard, who in the same year handed the castle over to Gilbert de Turberville, who preferred to continue living at Coity Castle.

The castle is notable for the high quality of the stonework, especially that of the Norman doorway. This is late 12th century, and was likely constructed at the same time as the high curtain walls and the two square towers which they support. Only the base of the west tower survives, but the south tower has three storeys. This was remodelled for living quarters in the 16th century, when Tudor windows and fireplaces were added.

Newcastle Castle is under the care of Cadw. It is open free of charge throughout the year.

It's just outer walls and a grass field in the middle. There's not much historical significance made of it. They call it a castle but it's also described as a Keep.. they are usually a tower in the middle surrounded by a wall.

Caerleon Roman Amphitheatre

Built around AD 90 to entertain the legionaries stationed at the fort of Caerleon (Isca), the impressive amphitheatre was the Roman equivalent of today’s multiplex cinema. Wooden benches provided seating for up to 6,000 spectators, who would gather to watch bloodthirsty displays featuring gladiatorial combat and exotic wild animals.

Long after the Romans left, the amphitheatre took on a new life in Arthurian legend. Geoffrey of Monmouth, the somewhat imaginative 12th-century scholar, wrote in his History of the Kings of Britain that Arthur was crowned in Caerleon and that the ruined amphitheatre was actually the remains of King Arthur’s Round Table.

Today it is the most complete Roman amphitheatre in Britain.
