A
monastery was established at Bangor in about AD 560 by
Saint Dunod (or Dunawd) and was an important religious centre in the 5th and 6th centuries. The monastery was destroyed in about 613 by the Anglo-Saxon king
Æthelfrith of Northumbria after he defeated the Welsh armies at the
Battle of Chester, which probably took place near Bangor-on-Dee; a number of the monks then transferred to
Bardsey Island and appear among lists of saints. Before the battle, monks from the monastery had fasted for three days and then climbed a hill to witness the fight and pray for the success of the Welsh; they were massacred on the orders of Æthelfrith. The scholar
Bede wrote that 1200 monks were slaughtered and only 50 escaped. is believed to have been built. The
Bangor-on-Dee Bridge, a five-arched stone arch bridge across the River Dee, dates its reconstruction to 1658 and it is believed to have been reconstructed to the designs of
Inigo Jones and replaced an older medieval bridge. A 1903
suspension bridge by
David Rowell & Co. is nearby at Pickhill Meadows. ==Transport==
