Trevor Basin is a canal basin on the Llangollen Canal, situated near Trevor, in Clwyd, between Llangollen and Ruabon.The basin was originally built at the northern end of the central section of the Ellesmere Canal, just 150yds north of the Pontcysyllte Aqueduct.With the abandonment of the planned extension to Chester, Trevor Basin became the terminus of the Ellesmere Canal itself.
