One of the first settlements on the eastern slopes of the Blue Mountains, Lawson was identified on early maps as 24 Mile Hollow–a name which was changed to Christmas Swamp for a few years. When the Blue Mountain Inn was opened in 1848, the locals adopted the name Blue Mountain for the village. This name was also given to the original railway station after the Main Western railway line was pushed through in 1867. The presence of a Blue Mountain on the Blue Mountains, however, became so confusing to visitors that the authorities stepped in and renamed the village Lawson in honour of William Lawson who, along with William Wentworth and Gregory Blaxland, were the first Europeans to cross the Blue Mountains in 1813.
