This year we have reviewed a wide range of projects – Heritage, Modernist, and current designs. We’ve visited Mansions and Stately Homes throughout Victoria, Tasmania and South Australia. We really hope you’ve enjoyed our posts and blogs, and look forward to even more interesting material in 2019. Over the next few weeks we will revisit a couple of our more popular stories.

Please don’t hesitate to call us or recommend our services should you require a genuine and passionate Heritage Architectural Service. For us, Heritage is a living and valuable reality.

Some of you may recall earlier this year we visited Fortuna Villa in Bendigo, a property steeped in the history of Gold Mining in that city, built by one of the Gold Rush period’s most successful miners, Mr George Lancell. It is a prime example of the largesse of the times. George Lancell attempted to provide some restoration to the devastation that resulted from Gold Mining in those times. His actions however were those of a patron, a man of a philanthropic nature.

Many of Melbourne’s finest mansions were built on the proceeds of Gold. Lancell did something most of them didn’t – he attempted some form of restitution and rehabilitation of his mining holdings.

Fast forward to today. Research undertaken by the University of Queensland’s Centre for Mined Land Rehabilitation estimates there are over 50,000 abandoned mine sites across the nation.

The real question is what can we do to rehabilitate or utilise these sites. An article published in The Conversation titled “Afterlife of the Mine: Lessons in how towns remake challenging sites” makes for interesting reading.

Old mine sites suffer many fates, which range from simply being abandoned to being incorporated into towns or turned into an open-air museum in the case of Gwalia, Western Australia.

The question of what to do with abandoned mine sites confronts both regional communities and mining companies in the wake of Australia’s recent mining boom. The companies are increasingly required to consider site remediation and reuse. Ex-mining sites do present challenges, but also hold opportunities for regional areas.

Old mine sites can provide a foundation for unique urban patterns, functions and transformations, as they have done in the past. It is useful to look at historical gold-mining regions, such as the Victorian goldfields, to understand how these sites have shaped the organisation and character of their towns.

Research by The University of Queensland’s Centre for Mined Land Rehabilitation suggests Australia has more than 50,000 abandoned mine sites. Some are in isolated places. But many others are close to or embedded within regional settlements that developed specifically to support and enable mining activity.

Abandoned mines present unique challenges for remediation:

  • the sites are large (sometimes enormous)
  • their landscapes are environmentally and structurally degraded
  • sites are often contaminated by substances used in processing – like arsenic in the case of historical goldmines.

These characteristics exclude mining sites from reuse for activities such as residential development. The sites are often considered fundamentally problematic. At times former mining sites have been reused opportunistically, accommodating functions and uses that could co-exist with the compromised physical landscape.
How have old mines shaped our towns?

The industrial patterns established during the Victorian gold-mining boom are traceable through observing the street layout and the location of civic buildings, public functions and open spaces of former gold-mining towns.

For example, in the gold-mining town of Stawell, a pattern of informal and winding tracks was established between mining functions. These tracks later provided the basis for the town’s street organisation and land division, including the meandering Main Street, which forms the central spine of the town.

Cato Lake, behind Main Street, was transformed from the tailings dam of the Victoria Crushing Mill. St Georges Crushing Mill and its associated dams became the Stawell Wetlands.

Other mining sites were transformed into the car park for Stawell Regional Health, the track for Stawell Harness Racing Club and the ovals for the local secondary college. A survey of public open spaces in Stawell shows that over time former mining sites accommodated most of the town’s public functions.

Open space in Stawell showing the correlation of past mining sites with public function: 1. Central Park – public reserve est. 1860s. 2. Cato Park and Bowls Club – was Victoria Co. Crushing Mill 3. Stawell Regional Health – built over a mullock heap associated with the St George Co. Crushing Mill. 4. Wetland Precinct – was part of St George Co. Crushing Mill 5. Stawell Harness Racing Club – was part of Wimmera Co. Crushing Mill 6. Stawell Secondary College and grounds – was part of Wimmera Co. Crushing Mill 7. Borough of Stawell reservoir (disused) – was part of Wimmera Co. Crushing Mill 8. Federation University (Stawell Campus) – was School of Mines and prior, St George Lead (surface diggings) 9. Stawell State School – public reserve established in 1865 10. North Park Recreation Reserve – was part of Galatea Co. Mine / Grants Crushing Mill 11. Stawell Leisure Complex – was part of Galatea Co. Mine / Grants Crushing Mill 12. Oriental Co. Mine Historic Area – was Oriental Co. Mine 13. Moonlight-cum-Magdala Mine Historic Area – was Magdala Mine / Moonlight Co. Mine 14. Big Hill reserve, lookout and arboretum – site of multiple claims including Sloan and Scotchman, Cross Reef Consolidated and Federal Claim

Many other Victorian goldfields towns developed in similar ways to Stawell. These towns have lakes or other water bodies in and around their central urban areas that were born out of mines.

Calembeen Park and St Georges Lake in Creswick and Lake Daylesford in Daylesford were all formed through the planned collapsing of multiple underground mines to create urban outdoor swimming spots.

Calembeen Park in Creswick is a swimming hole with a diving board that takes advantage of the extreme depth of the lake formed through collapsing several underground mines.

In Bendigo, the ornamental Lake Weeroona was formed on the site of the alluvial diggings. Other sites in these towns became parks, ovals, rubbish tips and public functions that could be accommodated on the degraded land.

Abandoned mine sites outside towns have also been used for unique purposes. Deemed unsuitable for use by the farming and forestry industries, these sites have developed into havens for flora and fauna, including endangered species. A 2015 article in Wildlife Australia magazine details instances of the Eastern Bentwing-bat and the Australian Ghost Bat adopting abandoned gold mines as replacement habitat for breeding and raising their young.

The neglect of other gold-mining sites has preserved historical remnants by default. The Castlemaine Diggings National Heritage Park in Victoria is one example. Here, water races, puddling machines and crushing batteries are hidden amid dense bushland.

The town of Gwalia in Western Australia, abandoned after its mine closed, has been transformed into a town-sized open-air museum.
And what uses are possible in future?

Historical gold-mining sites in or near towns continue to be adapted for unusual uses. The Stawell Goldmine on Big Hill in Stawell is being converted to accommodate the Stawell Underground Physics Laboratory (SUPL), a research laboratory one kilometre below the surface. Cosmic waves are unable to infiltrate the abandoned mining tunnels, so the conditions are ideal for exploring the theorised existence of dark matter.

In Bendigo it is proposed to use the extensive historical mine shafts under the town to generate and store pumped hydroelectricity. This scheme, recently explored as a feasibility study by Bendigo Sustainability Group, would use solar panels to create power to pump underground water up through the mining shafts to be stored at the surface. When power is required the water would be released through turbines to generate electricity.

The lack of demand for remediating sites for market-led uses (such as urban development, farming or forestry) broadens their potential for uses that might otherwise seem marginal or improbable, such as new forms of public space.

The scale and remoteness of many post-industrial mining sites in Australia – such as Western Australia’s Super Pit gold mine, which is 3.5 kilometres long and 600 metres deep – might mean that approaches to reuse different from those taken with historical goldmines are required. We don’t have to wait until a mine’s closure to think about how it might be used in the future.

Such dilemmas are already confronting municipal Councils on the edge of Australia’s largest cities. Quarries like the old Niddrie Quarry, west of Essendon, have been redeveloped creatively but there is a long way to go, with many such sites simply fenced off and abandoned.

The Brickworks of East Burwood is a similar site, and is now a real showpiece. In less environmentally aware times we simply filled them with industrial and domestic rubbish, then capped them – problem solved. Not really – most landfill sites became permanent open space with many emitting noxious gases.

Next year we will take a good look at some of these sites and the creative solutions modern town planners, architects and landscape architects are developing.

Till then, have a great holiday break and a great Christmas and New Year. See you in 2019.
