Originally called The Weatherboard after the �Weatherboard Inn� built in 1814, a year later the town was named Jamison�s Valley by Governor Lachlan Macquarie in honour of the colony's leading private citizen, Sir John Jamison. In July 1867, the first railway journey to the Blue Mountains left Penrith and traveled through to Weatherboard Station, where the train terminated. In 1879, the village took its name from a nearby system of waterfalls, which in turn were named for William Charles Wentworth, one of the men that headed the exploration to cross the mountains in 1813 and a friend of John Jamison
