Firth Park was donated to the city by steel magnate Mark Firth in 1875 as a public benefaction during his term as Alderman and Mayor of Sheffield. The park was formed from part of the estate of Page Hall (originally sited to the south), which was bought by Firth as a residence in the 1840s (all from Sheffield City Council 1997). Principal landscaping features in this polygon include the semi formal gardens and buildings at the north, and a wooded glen 'enhancing' a stream to the west of the park. The park fossilises a number of pre-existing boundaries with the grassed areas fossilising fields to the north of Page Hall and the wooded glen to the west corresponding to earlier piecemeal enclosures (possibly of former common or woodland) therefore the legibility of historic types within this polygon is significant.
