Horseshoe Falls is a 140m horseshoe-shaped weir designed by Thomas Telford to divert water from the River Dee into the beginning of the Llangollen Canal. The meter house on-site regulates over 12 million gallons of water drawn to the canal every day. In 2009 UNESCO designated Horseshoe Falls as part of the Pontcysyllte Aqueduct and Llangollen Canal World Heritage Site.
This project will enable the area to cope with increasing visitor numbers and will provide the opportunity to improve facilities and visitor flow at Llantysilio Green Car Park. Horseshoe Falls has become one of the major attractions in the Dee Valley, and the site has seen a significant increase in visitor numbers in recent years (over 100,000 visitors per annum); thus there is now a need to upgrade the facilities in order to meet this increased visitor demand and expectation.
