Picton is a small town located in the foothills of the Southern Highlands, around 90 kilometres south-west of Sydney. It is the main town and administrative centre of Wollondilly Shire.

Picton is home to many historic buildings, including two types of bridges not found elsewhere in the state: Victoria Bridge, a timber trestle bridge that crosses Stonequarry Creek, opened in 1897, and the Picton Railway Viaduct, a stone viaduct opened in 1863 and also crossing Stonequarry Creek. The viaduct is still in use by the railways.
