Municipal Council Depot. This polygon shows the site of Olive Grove Football Ground. One of the first purpose designed football grounds anywhere in the world (the 1891 map shows a pitch of modern dimensions surrounded by small stands and terraces and supported by embankments). The ground is unlikely to predate the 1870 construction of the Midland Railway line alongside which it is sited and the alignment of which it matches. Sheffield Wednesday are known to have played at this ground from 1887 (shortly after turning professional) until 1899, when Hillsborough became their home). The team previously played at the nearby Sheaf House Ground. The ground is no longer shown after 1905 when the Municipal depot which still survives alongside Olive Grove Road is first shown. Legibility of previous types is invisible.
