The location here of Brown's sawmill saw the first railway platform open as Brown's Siding in 1880. Three years later, in 1883, the name was changed to Medlow. The name Medlow has two possible origins; the first being derived from Megalong, an aboriginal name meaning 'valley below the cliffs'. The second is from a small town in the north of England near Brixton, called Medlow.
In the early 1900s Mark Foy purchased three properties on the cliff edge,including the Belgravia Hotel, and incorporated them into his hydropathic Sanatorium, the Hydro Majestic. Medlow bath had the bath added to it because of the therapeutic bath at the hydro majestic. The bath no longer exists. During World War II, the building was used by the American Army as a Base Hospital for servicemen wounded in Pacific Island battlefields.
