The Church of St. Catherine in Nummi suburb represents the medieval church building tradition. The construction began in the 1340s, the sacristy was completed first and the church later. Bishop Hemming and Bishop Thomas of Växjö consecrated the church on 22 January 1351.
Finnish National Board of Antiquities has named the church site as a national built heritage.
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.
