Seven Hills (NSW), NSW
By Lauren McCaleb · Reviewed by Dylan Duncan ·
Seven Hills is a suburb in Sydney's west, about 33 kilometres from the central business district, split between the City of Parramatta and Blacktown City. The Darug people, including the Warmuli and Toogagal clans, are the traditional custodians of the area. The name is thought to come from Matthew Pearce, a settler granted land in 1795, who called his farm Kings Langley and could reportedly count seven nearby hills from his property. The railway reached the district in 1860, and a platform opened at Seven Hills by 1869. Grantham Heritage Park preserves part of a former government poultry farm that was once a soldier settlement for returned servicemen, and the explorer Hamilton Hume was born in the district. Seven Hills Plaza has served local shoppers since 1960.
