Llangollen Canal not completed until 1805. To join the two halves up, a heavily engineered route from Trevor Basin via Ruabon and Brymbo to the River Dee at Chester was planned, but very little of it was built. Instead, the present route from Frankton to Hurleston Junction on the Chester Canal was constructed, and opened in 1805. To supply the system with water, a navigable feeder was built to Llantisilio, just beyond Llangollen, where the Horseshoe Falls weir was constructed on the River Dee to allow the water to be abstracted. As part of the Shropshire Union system, the canal from Hurleston
Llangollen of 4,079. Today Llangollen relies heavily on the tourist industry, but still gains substantial income from farming. Most of the farms in the hills around the town were sheep farms, and the domestic wool industry, both spinning and weaving, was important in the area for centuries. Several factories were later built along the banks of the River Dee, where both wool and cotton were processed. The water mill opposite Llangollen railway station is over 600 years old, and was originally used to grind flour for local farmers. In the late 19th century, Llangollen had a weekly newspaper, the "Llangollen Advertiser".
