Stanley Park is a 110 acres (45 ha) park in Liverpool, England, designed by Edward Kemp, which was opened on 14 May 1870 by the Mayor of Liverpool, Joseph Hubback. It is significant among Liverpool's parks on account of its layout and architecture. It has a grand terrace with expansive bedding schemes that were once highlighted by fountains. It includes the 1899 Gladstone Conservatory, a Grade II listed building built by Mackenzie & Moncur of Edinburgh. 50–60% of the land consisted of open turfed areas, suitable for sport, with most of the rest being laid out as formal gardens and lakes. Kemp designed a horse-riding track, though it did not catch on and was restyled as a cycle track around 1907.
