Restoring a piece of Glen Forrest’s heritage

RESTORATION works are currently underway to preserve the historic stone boundary wall at Glen Forrest’s iconic Octagonal Hall, with the Shire of Mundaring engaging specialist stonemason Ron Coltman from Art in Stone to lead the project.

Built in 1897, the Glen Forrest Hall, originally known as Forrest Hall, has long been a cornerstone of the local community, hosting everything from agricultural displays and dances to meetings and elections.

Over time, the site has evolved and in 1935 local volunteers constructed the now heritage-listed stone wall that frames the property today.

Made from granite with cement pillars and once linked by chains, the wall has stood for more than 80 years as a defining feature of the hall and its surroundings.

However, age and environmental impacts have taken their toll and deterioration of the concrete pillars and internal rusting have led to cracking and structural instability, prompting the need for careful restoration to retain both its integrity and historical value.

With more than 35 years’ experience restoring heritage structures across Australia and the UK, Mr Coltman brings a deep respect for traditional craftsmanship and the stories embedded in each project he undertakes.

“Every piece I work on has a story to tell,” he said.

“It’s not just about repairing stone. It’s about preserving the history, the people, and the craftsmanship that went into creating it. This wall is a real reflection of community effort and local identity.”

Already, the restoration has revealed fascinating insights into the ingenuity of its original builders.

During early works, Mr Coltman discovered that the concrete pillars had been reinforced using sections of old train tracks – an inventive solution that speaks to the resourcefulness of the 1930s community.

He also identified the use of black dolerite within the wall, the same material once used as a railway bed for the Glen Forrest train line, further tying the structure to the area’s transport and industrial heritage.

In a remarkable full-circle moment, Mr Coltman’s
connection to the wall extends beyond the present-day works.

Some years ago, he met one of the original stonemasons believed to be involved in its construction, Italian craftsman Johnny Muciarone.

Before his passing, he gifted Mr Coltman one of his old tungsten chisels, which he believes to have been used on the very wall now being restored.

“To be using Johnny’s chisel on this project is incredibly special,” Mr Coltman said.

“It’s like continuing his work, carrying forward his legacy. There’s a real sense of continuity in that – it’s something you don’t come across often.”

The restoration process will carefully stabilise the existing structure while retaining as much of the original material as possible, ensuring the wall continues to contribute to the heritage significance of the site.

The works are expected to be near completion,
after which the restored wall will continue to stand as both a physical and symbolic connection of the past to the present, and the preservation of an important
piece of Glen Forrest’s history for generations to
come.
