Balwyn was named after the 1858 vineyard and rural retreat of The Argus newspaper editor Andrew Murray. The property was located on Balwyn Road and according to Mr Murray, the name was Gaelic for “home of the vine”. Balwyn’s first town centre was near the intersection of Balwyn and Whitehorse Roads, containing a few shops, a blacksmith and the athenaeum or mechanics’ institute.
