The aqueduct's construction, which began in 1795, was revolutionary at the time. Telford, rejecting all precedents, designed a cast-iron trough 3.25 metres wide and 307 metres long, laid along the top of 18 stone piers to carry the waterway high above the river.For the adventurous, it is possible to hire a canal boat both at Chirk Marina or at Trefor Basin and cross the aqueduct by boat. Alternatively there are canal boat trips available for those who want to sit and take it all in.  Discovered at Pontcysyllte Aqueduct, Wrexham, Wales. See more at Trover
