The construction of Paide order castle was started in 1265 under the leadership of Konrad von Mandern. The original tower of Tall Hermann was octagonal with the height of over 30 meters and the thickness of the walls of about 3 meters.
At the beginning of the Livonian War the Russians repeatedly besieged Paide, but only in 1573 they finally managed to invade Paide. After that it changed hands several times until the Swedes got it in 1608. In 1638 they removed Paide from the list of castles.
The rampart tower and castle ruins were first conserved at the end of 19th century. In 1913 a park was planted on the hill. In 1941 Soviet soldiers destroyed the rampart tower, the symbol of both Paide and Järva County. To celebrate the 650th anniversary of the St. George's Night uprising the tower was restored in 1993. Today it houses a museum.
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.
