Suburb built on Dharug land north-west of central Sydney which was first used by Europeans for timber-getting, and later for farms and orchards. The suburb grew steadily after the arrival of the railway line in 1887.
The area that became Pennant Hills was Dharug country before the Europeans arrived. A convict timber-getting camp was set up in 1816, but by 1830 the forest had been felled, and farms and orchards covered the land. When the railway came through in 1887, produce could be taken to market more quickly, and the town grew, catering for travellers and holidaymakers.
