Field Mill, currently known as One Call Stadium for sponsorship reasons, is a football ground in Mansfield, Nottinghamshire, England, and the home of Mansfield Town Football Club. It is the oldest ground in the Football League, hosting football since 1861, although some reports date it back as far as 1850. The stadium has a capacity of 10,000 when fully open, but due to safety restrictions, it currently holds 9,186 The stadium once hosted a pop concert under the previous owner, Keith Haslam, but the sale included a clause preventing use for non-sports events until 2032. The ground is now fully owned by John and Carolyn Radford after a series of payment installments from 2012 were concluded in early 2019. History Before Mansfield Town 'Field Mill' was originally the name of a large, stone-built, water-powered textile-mill with its own mill pond. The mill was located directly across the road from the present ground, being one of several situated along the River Maun water course supplied from a nearby reservoir. The mill was demolished in 1925. The club site on Quarry Lane was originally used as a recreational area for employees of the Greenhalgh & Sons Works, who rented the surrounding areas from the Duke of Portland for their cotton-doubling business. One of the Greenhalgh sons was Harwood Greenhalgh, a Mansfield-born footballer who played for Notts County, and represented England in the first ever international football match. The Greenhalgh's team played at Field Mill under various incarnations, including 'Greenhalgh F.C.', 'Field Mill Football Club' and 'Mansfield Greenhalgh'. A team representing Greenhalgh & Sons also played cricket at the ground for many years, while the late nineteenth century saw athletics and cycle-racing on Quarry Lane. An 1894 merger with Mansfield Town (no relation to the current club) to form Mansfield F.C. saw Field Mill become almost exclusively a football ground. The ground was used by Mansfield Mechanics FC from 1912 to 1916. The home of Mansfield Town Mansfield Town first started playing matches there in the 1919–20 season, however for the first two years it was also used as a cricket ground by the Mansfield branch of the National Federation of Discharged and Disabled ex-Servicemen's Societies (DDSS). In 1921, the DDSS's lease on the ground ran out, and the ground was sold by its owner, the Duke of Portland, on the condition that it would only ever be used for sporting purposes. The
