you want to sail over it on a narrow boatpmk..............a 120' drop and on one side, whilst you are sitting on your boat all that keeps you from a fall to iternity is a 6" thick piece of cast iron making up the canal aquaduct :angel:.......a fantastic buzz if you have a head for heights.
On my first sailing over, my father, who flew mosquito's in the pathfinders during WW2, and who was on a trip with us locked himself in the bog on the boat as he found it too frightening.

.............you want to try it.

There are two of them close together , the Pontychisyllte and the crick aquaducts near Llanngollen.
British engineering at it's finest.

I think the one in the picture is the Crick aquaduct with Crick tunnel in the background??
