Before Europeans settled the region, the area around Penrith was home to the Dharuk Aborigines and was known as Mooroo Murak. Artifacts dating to 47,000 years ago have been identified in the district. In 1815 when the Blue Mountains Road reached Penrith, a courthouse and jail were also built. Penrith's first European name was Evan, but in 1818 Governor Lachlan Macquarie renamed it after the town of Penrith in Cumbria, in England's Lake District. Penrith was first linked by railway to Sydney in 1863. The line was electrified in 1955. Population (1991) 152,650.
