Llangollen Canal agreement had been reached in 1802 on a route from Tilstock Park to Hurleston Junction, on which work started immediately. It was completed on 25 March 1805. In order to keep the system supplied with water, an Act of Parliament obtained in 1804 had authorised the construction of a navigable feeder from the north end of Pontcysyllte aqueduct to LLangollen on onwards to Llantisilo, where the Horseshoe Falls weir would be constructed on the River Dee. Once this opened in 1808, the system was not short of water. The Ellesmere company attempted to buy out the Chester Canal in 1804,
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".
