Hillsborough Park was originally laid out as part of the grounds of Hillsborough House. The house was constructed in 1779 to a design by Robert Adam. The park was laid out in the tradition of English landscape gardens consisting of native tree species planted in naturalistic groups in open parkland. The park also includes a lake, a ha-ha and a walled garden. Originally the park was double the size extending to Dykes Hall Road, Wadsley Lane and Penistone Road. Sheffield Corporation bought the park in 1890 and opened it to the public in 1892. The house was acquired in 1903. Together, the park and house are one of the few remaining examples in Sheffield of an 18th century house in its surrounding parkland and forms a conservation area. Legibility is significant due to the overall coherence of the surviving features. The suburb of Hillsborough takes its name from the house.
