The mighty St. Gallus church from the 17th to 18th century sits enthroned above the city. The church was constructed on a pre-Christian cult site and was redesigned on multiple occasions by the famous baroque master builders of the Bregenz Forest.
The church was built to the site of pre-Romanesque church founded around 450 AD. Irish monks Columbanus and his brother Gallus founded the destroyed church in 610 AD and ordered to rebuild it.
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.
