Mansfield Town Football Club Open Day, 14/07/2013. Field Mill stadium, League Two. Rows of traditional terraced houses situated behind one of the stands at Mansfield Town's Field Mill stadium during an open day held for the club's supporters. Mansfield Town achieved promotion back to England's Football League by winning the Conference National in season 2012-13. Field Mill was the oldest ground in the Football League, hosting football since 1861 although some reports date it back as far as 1850, with Mansfield Town having played there since 1919.
