History
The distinctively shaped weir, which is Шаблон:Convert long, helps create a pool of water that can enter the Llangollen Canal (via an adjacent valve house and flow meter). The canal west of Pontcysyllte Aqueduct and the construction of the weir were authorised by an Act of Parliament obtained in 1804 by the Ellesmere Canal Company. The canal was a navigable feeder, which supplied water to the Ellesmere Canal beyond Pontcysyllte, and to the Chester Canal, to which it connected near Nantwich. Thomas Telford was the civil engineer responsible for the design, and the canal and feeder were completed in 1808.Шаблон:Sfn
The weir was an important factor in the retention of the canal to Llangollen when the owners of the entire Shropshire Union system, the London, Midland and Scottish Railway, decided to close much of the network in 1944. They retained the line of the former Chester Canal and the Ellesmere Canal from Nantwich to Ellesmere Port, the branch of the Chester Canal to Middlewich and the former Birmingham and Liverpool Junction Canal main line from Nantwich to Wolverhampton. Because Horseshoe Falls was a major source of water to that system, the canal from Llangollen to Nantwich, including the great aqueducts at Pontcysyllte and Chirk, was retained purely as a water supply channel. This action enabled the canal to survive until it was taken over by British Waterways following nationalisation in 1948. With the steady decline in commercial traffic, British Waterways negotiated with the Mid and South East Cheshire Water Board, and the canal is used to transfer water from the Dee at Llantysilio to a reservoir near Hurleston Junction, to the north of Nantwich.Шаблон:Sfn In 2009, some Шаблон:Convert per day was conveyed along the canal.Шаблон:Sfn Under British Waterways, the canal has become one of the most popular cruising canals in the country.Шаблон:Sfn The final Шаблон:Convert from Llangollen to the Falls is not navigable by motorised boats, as it is not wide enough for vessels to turn round,Шаблон:Sfn but the towpath extends along the bank right up to the Falls.Шаблон:Sfn
Since 2009, the weir has been part of a World Heritage Site, which covers Шаблон:Convert of the Llangollen Canal from just west of Horseshoe Falls to just beyond Chirk Aqueduct. The canal was awarded World Heritage status because of the bold civil engineering solutions needed to construct a canal with no locks through such difficult terrain.[2]
