first grandstand was erected in 1922 along the length of the west side of the ground, with the other three sides mounds formed from ash from nearby coal mines, all completed by 1926. In 1929, using the money from the cup run of the previous year, a covered stand was built on the Bishop Street side, occupying a similar position to the Bishop Street Stand of today. The first terracing was built during the 1930s from railway sleepers, and lasted 20 years. Floodlights were installed and officially switched on by Billy Wright on 5 October 1961 before the Football League Cup game against Cardiff City. Shortly after World War Two, concrete terracing and a PA system were introduced. The club bought land to the West side of the ground in the mid-1950s, just before the supporters' club funded the building of the new North Stand, at a cost of £30,000. In the 1960s a new grandstand was erected on the west side of the ground after being purchased from Hurst Park Racecourse in Surrey. The stand itself cost £30,000, although the final amount spent was considerably more than this once the cost of transportation and reconstruction is taken into account. The stand was first used in 1966, but it was not fully completed until 1971. Between 1984 and 1986, Field Mill was home to a rugby league team called Mansfield Marksman. After plans to relocate to a new all-seater stadium were scrapped, work began in July 1999 to completely modernise Field Mill. The North Stand, Quarry Lane End and West Stand were completely demolished and new stands built in their place, including a two tier stand on the west side of the ground. The redeveloped all-seater stadium was officially opened by John Prescott on 28 July 2001, six months after work had been completed. In July 2005, safety officials temporarily restricted Field Mill's capacity to 5,000 when fire safety certificates could not be located. The ground's capacity was again reduced in May 2007, from 9,368 to 4,684, when Nottinghamshire County Council, who enforced the reduction, cited a poor standard of stewarding and a lack of a pro-active approach to safety. In July 2007 the capacity was raised to 6,553 following an inspection from safety officials, but was reduced back to 4,684 in September after visiting Chesterfield supporters were given too many tickets by mistake. Field Mill's capacity was then increased
