Sulejów Abbey was a Cistercian abbey founded in 1176 by the duke Kazimierz II the Just. The town of Sulejów grew up round it. The most notable parts of the abbey are the Romanesque church of Saint Thomas Becket of Canterbury and Romanesque fortifications which stopped the Mongol Hordes in the 13th century.
The monastery was dissolved in 1810. After many years of industrial and business use the surviving buildings are now used by the present parish.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.
