Mount Martha has its roots dating back to the 1840s when the township's major role was that of farming. The Briars Homestead in the town's east was constructed from 1848 to 1851 and was used by Alexander Balcombe until 1876 as he farmed the land surrounding it and tended to of vineyards. The homestead was named after the lodging of the same name in Saint Helena. Dame Mabel Brookes collected Napoleonic memorabilia which was also donated to the Mornington Peninsula shire; some is on display at the house.
