The Historical Markers project is an ongoing photographic project spanning Melbourne and the United States of America. An inversion of the idea of the historical marker as placard or sculpture signifying an event at a site which has left no trace, this project aims to build a catalogue of photos of architectural blemishes and ruptures as evidence of an event or happening that we have no awareness of. These architectural markings are the indicators of past event or action. A collaboration of material, they are a marker of force, whether it be natural or man made is often not evident. They have a personality, a feeling. They hint at a history displayed as form, but few questions are answered. This seemingly insignificant mark, reveals a proof of pasts in the present and remind us that the structures surrounding us are also susceptible to the passing of time.
