The AberValley.
From time immemorial people who wished to travel from outside North Wales onto Anglesey would probably travel to Conwy. From Conwy they would then have to cross the river at an area around Tal-y-Cafn, through Rowen and across the pass over the hills and down to Aber. The Aber Valley area would have been very difficult to get to as it was cut off from east by the Conwy river and until bridges were built the only way in was by ferry or steeping stones it was not a friendly river to cross .There is a legend that a giant couple (husband and wife) were crossing the pass with building stones to build their house. The husband had two large stones for a door way and the wife had an apron full of stones for the walls, as they went on their way they met a cobbler coming in the opposite direction with a number of worn out pairs of shoes around his neck. The giant husband asked the cobbler how far it was to Anglesey. Scared that the Island would be over run with giants the cobbler told them that it was so far he had worn out the shoes around his neck on his journey so aghast was the giant man that he though down his stones giving the pass its name bwlch-y-ddeufaen (the pass of the two stones). The wife dropped her stones which are still there (in fact they are a bronze age burial cairn) this ancient path is called the Roman road. The Romans came to the area in about AD61 the pass would be ample for foot traffic but once army’s were required to haul heaver items of artillery the pass would be to steep, slow and open to ambush and so other ways were sort around the area. One reason why the Romans came to the area may have been to cut the supply of food from Anglesey (Mon, Mam Cymru) mother of Wales, which supplied the mountainous region and marauding troops with grain.
