The first building on the site of current Sion Cathedral was built in the 9th century and destroyed by fire in 1010. The next Romanesque cathedral existed until the 15th century. The existing bell tower dates from the 13th century. The nave was rebuilt in Gothic style between 1450 and 1500. The cathedral contains several Roman inscriptions, 15 altars, and many fonts.
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.
