Oamaru’s main drag owes its expansive girth to the need to accommodate the minimum turning circle of a bullock cart. The town's grand pretensions reached their peak in the late 19th century in a series of gorgeous buildings constructed from the milky local limestone (known as Oamaru stone or whitestone), with their forms reflecting the fashion of the times; there's a particular emphasis on the neoclassical.
Impressive examples include the Forrester Gallery (at No 9, built 1883), the ANZ Bank (No 11, 1871), the Waitaki District Council building (No 20, 1883), the North Otago Museum (No 60, 1882), the Courthouse (No 88, 1883) and the Opera House (No 92, 1907).
