It will mean the Denman’s extensive collection can be properly stored and catalogued.

Denman treasurer and former committee president Morgan Sant, one of several people who spoke at the Great Gallery’s recent opening, likened the project to preservation of local history.

“We can look after our collection in a way we never could before,” Mr Sant said.

Funds for the new wing came from the federal, state and local governments and the Lady Denman committee also contributed of its own savings.

Shoalhaven Mayor Paul Green said the three tiers of government had worked well together.

“This is a classic example when three levels of government get it right and come together,” he said.

“This is about leaving a legacy for future generations.”

Cr Green, Federal Member for Gilmore Joanna Gash and Senator Michael Forshaw, representing the federal government, were all given a tour of the Great Gallery.

They were shown the large Vera Hatton Gallery, which will be used for major exhibitions like the See Change Festival, the conservation room, the multimedia theatre and permanent exhibition room, which will highlight Jervis Bay’s natural beauty.

Cr Green said it was fantastic to look around to see all the space dedicated to local heritage and culture.

President of the Lady Denman Heritage Committee, Margaret Britton, had the honour of taking some of the dignitaries around the Great Gallery.

It was a proud day for Mrs Britton and her fellow volunteers.

“The future of the Lady Denman is bright,” she said.

“I would like to thank the volunteers, who should be justifiably proud.”

The construction project created 77 jobs and pumped much needed money into the local economy.

The cost of the project will surpass $500,000.
