Historians and heritage specialists are at odds over which colonial building in NSW is the oldest intact house in Australia: Experiment Farm Cottage, or Elizabeth Farm House. This feature explores the dispute, the detective work which has cast new light on the established interpretation of Australia's colonial built heritage, and the difficulties inherent in trying to understand the past through extant sources such as images and buildings. It's also the story of the man behind the building of Experiment Farm Cottage: the Irish surgeon John Harris.
