The colossal Heidenreichstein castle situated in the moorlands to the northwest of the Waldviertel is the largest and best preserved medieval water castle in Lower Austria. The oldest parts of the castle are dated back to the 12th century. It has never been in enemy hands since its construction. The walls of the four wings, the three corner turrets and the keep are up to four metres thick. A guided tour through the three-storey living apartments with spiral staircase and arcades discloses highly remarkable interior fittings including Gothic furniture, articles of daily life and portrait paintings.
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.
