The Mere in Ellesmere is a legacy created by the retreating ice age. An artificial island was built in 1812 where grey herons nest. In 1791 the Duke of Bridgewater & his associates got together in a local hostelry & decided that Ellesmere could become the hub of a new canal network. They raised over £1million in a day & the Llangollen canal was born. Thomas Telford was commissioned to design and oversee it. The crane and canal-side warehouse give a hint that this was once a busy working location
