Join Working Heritage as they open the gates to one of Melbourne's most intriguing heritage sites. Discover the hidden history of Jack's Magazine on a guided walking tour led by Andy Calvert, who has been sharing stories from the site since 1993. With a gift for storytelling and an encyclopaedic knowledge of the site, Andy brings its military, industrial, and architectural past to life. Explore the tunnels, buildings, and blast mounds and don't miss the sweeping views of the Melbourne skyline from atop the mounds. The impressive, and somewhat concealed, property of Jack's Magazine was opened in 1878 to safely store gunpowder imported into the colony of Victoria. The site later provided storage for other dangerous materials used in the ammunition factories that linked the building to the area's broader industrial military precinct known as the 'Arsenal of Australia'. Incorporating a large site on the banks of the Maribyrnong River, the property includes two magazines, a variety of ex-storage and administrative buildings, blast mounds, tunnels, a canal, and an imposing perimeter bluestone wall.
