Tree of Knowledge
Memorial
To their credit, the client took our collaborating partner, Brian Hooper Architects, initial advice and saved both the relic tree's root ball and branches. In this way the Tree remains connected to the ground (to Country) and to its history. A history visible through a new glass floor and the relic branches reaching out to the lost canopy.

(Translation #04 — Tree of Knowledge Memorial)
By defining the space left behind by the Tree of Knowledge we are reminded of both its loss and its presence. With its presence the stories of the events which took place beneath it, and the changes that resulted, once again come to life.

Quotes
This remarkable structure may not have existed and the tree been lost if not for the compelling vision, intelligence and tenacity of the architects and their collaborative relationship with mayor Rob Chandler, who supported, promoted and carried this project through many difficulties. This important work demonstrates the transformative power of architecture and the pivotal role good architects can play in public advocacy and community contribution.
National Jury. RAIA Lachlan Macquarie Award for Heritage Architecture
Thank you and your team for your vision and expertise that has created a fitting Memorial to a truly national icon 'The Tree of Knowledge. I do appreciate the close consultation between yourselves and Council throughout this process. This project would simply not have been possible without the vision, the passion and the professionalism
Rob Chandler Mayor of Barcaldine (2009)
... perhaps the most powerful story of collaboration, leadership and perseverance between client and architect ... The architects have amplified the beauty, history and serenity of this important place through their work, and through their ability to communicate a clear vision for the project to the community, often at critical, pivotal moments during the project’s delivery.

With the relic tree and the negative space of the lost canopy visible, with movement once again visible overhead, and with shadows flickering on the red earth, the Tree of Knowledge once again comes alive, and with it the history and stories associated with it.
By strategically removing the car parking spaces immediately adjacent to the tree, and by providing the passer-by with a brief view to the lost canopy, visitors are compelled to stop. The resultant ‘walk’ forces visitors to slow down and engage with the town, its locals, and the memorial.
