An attractive and vibrant public space, The Octagon has long been the centre of Dunedin. Walkers will learn how the space has evolved, and how Dunedin has evolved. A comprehensive introduction here outlines Dunedin's pre-Colonial, Scots Free Church settlement and gold-rush years, and touches on challenges and opportunities the city faces now. Dunedin's fortunes have always waxed and waned; we learn how this has been reflected in standout Octagon buildings including St. Paul's Cathedral and Dunedin's Municipal Chambers.

Entry to this building is no longer guaranteed, but we do study the Cathedral and discuss why it occupies such a prominent site in what was a staunchly Presbyterian town. We account for the contrasting architectural styles on display, and contemplate changes made and proposed in the wake of the Cathedral's 2020 fire.
