Extent Heritage WA will take visitors on a guided walk to the top of the terrace, to gather around the foreboding and forlorn Barracks Arch in the late afternoon. Sitting there all by itself, on its own little island, and as if seemingly still guarding the city of Perth, Team Extent will explore the fabric of this strangely iconic piece of Perth's history. Together the group will investigate what's been left behind and recreate what is missing by uncovering its own research and invite the interactive contributions of those who join them. As the sun sets, and the city quietens, visitors can be on watch with the arch and discover together if walls really do speak.
