The settlement, then called Upper Dunstan, swelled to a population of about 14,000 during the gold rush in the 1860s.
It now has about 1000 people and celebrates its past through its historic district of late-1800s buildings.
In May, the Central Otago District Council banned certain large trucks from traversing the precinct.
In the lower-right-hand corner is Dunstan Hospital, which caters for much of Central Otago and Wanaka, excluding the Maniototo.
