On the hourly 5A bus from Trevor to Wrexham in Northeastern Wales, I was wondering how UNESCO World Heritage program took me to this corner of United Kingdom to see the unknown aqueduct which I hardy could make a proper pronunciation or even spelling, an engineering masterpiece, the Pontcysyllte. I walked along the Llangolan canal until I reached the aqueduct passing many boats which were mooring waiting for the tourist season to begin in the next couple of months. The aqueduct was indeed impressive especially for its height from the River Dee, its column and ached bridges really remind me the equally impressive of ancient Roman aqueduct of Segovia in Spain. To appreciate the height of the bridge I decided to walk down to the River Dee level, but it was very exhausted when I had to walk back to the aqueduct level again. Then I crossed the Aqueduct, it was a nice design to have walkway on the bridge too, so that I could saw the waterway and the surrounding view. The view along the canal was also lovely but nothing special and some part was similar to another World Heritage Site in Belgium, the old Canal du Centre. I looked around the place together with 5-10 tourists for about 40 minutes and found out nothing I could do more in this place, so I hurry walked back to the bus stop to catch the bus back to Wrexham before continuing my trip to Conwy for another World heritage Site. For me, it was a fine site as the aqueduct was impressive, the surroundings were also OK, however, since I already saw many industrial sites in England, the birthplace of Industrial Revolution, I started to feel rigidly bored, the place could not evoke any of my enthusiastic, also few information at the site to tell the significant of the place. The berthing boats along the canal looked more interesting for me!
