Rothenthurn ('red tower') castle may have existed since the 11th century. It was an estate of the Counts of Ortenburg and their successors, the Counts of Celje. A castle is documented in 1478, when the area was held by the Meinhardiner House of Gorizia. The present-day Renaissance building with its chapel was erected from the early 16th onwards, it was acquired by Christoph Khevenhüller about 1525 and afterwards in the possession of several local nobles over the centuries. Today the owners run the castle as a lodging establishment.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.
