Knottingley is a town within the metropolitan borough of the City of Wakefield in West Yorkshire, England on the River Aire and the dated A1 road previously it was bypassed as the A1(M). Historically part of the West Riding of Yorkshire, it has a population of 13,503, increasing to 13,710 for the City of Wakefield ward at the 2011 Census.
Until 1699, it was an important inland river port but, in that year, the Aire was made navigable as far-off as Leeds, which soon surpassed it. Knottingley continued as a centre for boat building into the 20th century. In the late 19th century, it started glass manufacturing. The town is served by Knottingley railway station.
After 1870, the town became known for glass manufacturing. In 1887 Bagley’s Glassworks purchased the rights to the first bottle-making machine, invented by a Ferrybridge postmaster. There is a Bagley’s Glass gallery in Pontefract Museum.
Close to Knottingley is the Ferrybridge Power Station, which has the largest cooling towers of their nice in Europe. Three of these towers collapsed in tall winds in 1965. These towers can be seen for miles around. One of the oldest purpose-built cinemas in England, located in Aire Street, has been converted into flats.
The town was the last in the United Kingdom to have a working deep coal mine, Kellingley Colliery, until it closed in December 2015.
