Barcaldine Tree of Knowledge Memorial

Barcaldine Tree of Knowledge Memorial by Brian Hooper Architect and m3architecture, architects in association, won the Lachlan Macquarie Award for Heritage at the AIA's 2010 National Architecture Awards.

In 1891, a small outback Queensland town was the site of an event that shaped Australian history – the great shearers strike which ultimately gave rise to the formation of the ALP. The shearers met under a huge ghost gum in the main street of Barcaldine, the so-called Tree of Knowledge, which became a symbol of the workers’ struggle.

Over time the tree had suffered and in 2006 was poisoned. Although the tree is dead, the history lives. Thanks to the remarkable efforts and advocacy of the architects and the support of a small community and three levels of government, Barcaldine now hosts the Tree of Knowledge Memorial.

Here architecture rescues the object and preserves, explains and honours the memory in a powerful, haunting, enigmatic structure. From twenty kilometres out on the Longreach road, a mysterious form appears, locating Barcaldine in the seemingly endless flat landscape and drawing the traveller to the town. Gradually revealed is a huge cube, a sheath of suspended timber shards, each chamfered end like a leaf, which carves out in negative the ghost of the tree.

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. Barcaldine has a source of great civic pride and an attractant to the town, and Australia is richer for the preservation of an historic icon of national significance.
