After undergoing considerable development in the 1920s and 1930s, the ground suffered heavy damage in World War II. It reopened in time for the resumption of the Football League in 1945, and underwent further improvements in the 1950s, including the installation of floodlights and a new double-decker grandstand. The ground remained relatively unchanged until 2001, when construction of three new all-seater stands began. The work was completed in 2002, and after further work the stadium became all-seater in the summer of 2007.
