The Ronde Lutherse Kerk or Koepelkerk is a former Lutheran church designed by Adriaan Dortsman (ca. 1636-1682). It was opened in 1671. The organ was built by J Batz in 1830 and it was restored in 1983 by Flentrop Orgelbouw. In 1882 it was rebuilt after a fire. In 1935 the Lutherans left the building and it became a concert hall.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.
