Last Saturday I took a trip to the Pontcysyllte Aqueduct in north Wales. It is a navigable aqueduct which carries the Llangollen Canal (and its canal boats) over the valley of the River Dee. It is the longest and highest aqueduct in Britain. It is quite daunting to walk the thousand feet along the path by the side of the water. To one side you have the hand rail and the other side of the water (to the left in the above photo) is over a hundred foot drop. Having done a bit of research on this aqueduct I can tell you it was built by Thomas Telford, opened in November of 1805, took ten years to design and build and cost £47,000 (at the time). I ended up arriving at this location a little late in the day. By the time I had walked across it the sun was setting behind the hills so I could walk down to get a photograph looking up at the aqueduct, not to worry though, because I can always go back (and I will)…enjoy.
