Gwynedd Uwch Conwy (Welsh:Gwynedd Above the Conwy) or Upper Gwynedd is the portion of the former Kingdom of Gwynedd found to the west of the River Conwy (but usually excluding Anglesey) in north Wales. This area was typically the bastion of native Welsh resistance to English subjugation and occupation attempts during the Middle Ages and the location for the principle royal estates and fortresses of the ruling House of Aberffraw.
