Gottlieben village is first mentioned around the end of the 10th Century as Gotiliubon. It was originally part of the land owned by the Bishop of Constance. In 1251, Eberhard von Waldburg built a castle that served as the residence of the Bishops. After the Swabian War in 1499 the episcopal chief constable managed the village and the local low court from the castle until 1798. The court included Engwilen, Siegershausen and Tägerwilen as well as Gottlieben and made up the Bishop's bailiwick of Gottlieben. In 1808 the castle became private property. In 1837 it was renovated in a neo-gothic style.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.
