St. John's Church was built in the 13th century, probably between 1234-1297. It was originally home of the Dominican monks, but over the centuries fell into the possession of the Lutherans. It has also served as an arsenal for the city.
The most notable features of this unheralded church are the impressive 15th century sculptures of St. Peter and St. Paul which adorn the the 18th century altar. According the legend two monks who were bricked to the southern wall during the construction. They spent all their life long and were fed trough a window from the outside.References:
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.
