Porth-y-Tŵr (Welsh for Tower Gate) is a gatehouse and bell tower overlooking St Davids Cathedral. It is the sole survivor of four medieval gates to the walled Cathedral Close. The 13th-century octagonal tower, adjoining the gateway, now contains the cathedral's bells.
What is nowadays the bell tower was used by the bishops of St Davids for their consistory court and a record office for the episcopal see. The south tower and the range of rooms above the gate were used as a council chamber. Well appointed apartments, suitable for the mayor, were accessed via a doorway on the town side of the tower.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.
