39 metres (127 feet in old money) above the Dee Valley to be more accurate. Yes, we went over to Pontcysyllte Aqueduct in Wrexham County Borough this morning. Although the sun popped out occasionally to remind us of its existence, the temperature struggled to get any higher than 12°C which seemed colder at height. Still, it was a reasonably bright day and we had some magnificent views from our vantage point in the sky!
Looking down at Cystylltau Bridge, which was constructed during the 17th century.
Looking west towards Berwyn Railway Viaduct
The aqueduct carries the Llangollen Canal across the valley and, as you’d expect, this particular stretch of water is popular with narrowboats although, today, we saw two teams of canoeists crossing over as well. There is a towpath on one side of the aqueduct, providing great views over the River Dee as it courses through the valley below, and this was busy with people crossing from both sides.
This dog is clearly used to being chauffered across the aqueduct.
It certainly makes a difference looking down on the green tree canopy below, rather than leaning back and looking up. As you can see from the photographs, the foliage is absolutely flourishing everywhere.
The cast-iron trough that carries the water has to be cleaned and maintained of course. This happens every five years: each end is closed and a plug opened to drain the water into the River Dee below. It’s basically the same as emptying your bath at home, although this is a slightly bigger bath!
The words on this sculpture by Anthony Lysycia are from Sir Walter Scott who had described the aqueduct as ‘the stream in the sky’. Scott had also wondered how fishes could swim above flying birds, hence the central depiction.
Thomas Telford and William Jessop get the credit for building the aqueduct, although they did get a little bit of assistance from the more than 500 men that were also involved in the work over a period of ten long years. There’s a little museum at one end of the aqueduct where you can learn all about its history. Quite fascinating.
While there are railings on the towpath side, there aren’t over the far side: I’ve been over in a narrowboat only the once and remember looking out of the window and not seeing anything other than sky on that one side! It really was a thrilling experience (a bit hairy, to be honest). The aqueduct is well worth a visit, whatever form of transport you opt for.
Although holes were drilled to take railings, they were never actually added to the far side of the canal’s cast-iron trough.
While this looks like you’d get a close view of the valley below, it might not be to everyone’s taste!
