IT WAS built in 1912 and while once it was the centre of power in the local area, it is now home to the Mid Richmond Historical Society in Coraki.
The old Woodburn Shire Council Chambers is turning 100 this year and this weekend there will be a reunion of council staff and interested parties to help celebrate.
"The weekend is going to be much bigger than we expected," society secretary Margaret Jennison said.
"So many people who worked here on council are coming."
About 200 people are expected over the weekend and there will be plenty of information and displays for them to enjoy.
There will be antique appraisals, displays of the recently restored Buckendoon and Bungawalbin Honor Rolls, a demonstration of gramophones by John Auckram, a visit from the Vintage Car Club and much, much more.
Woodburn Shire Council was formed in 1907 and started using the building once it was finished.
One claim to its fame was the appointment of the first female shire engineer in Australia, Miss Esme E Martens at the age of 27 in 1967.
According to history, the town clerk told the council they had gone 'stark raving mad' appointing a woman.
A few years later this same town clerk married Miss Martens.
The celebrations go all weekend, starting at 9am on Saturday and 10am on Sunday.
A special invitation is extended to people who worked in the council and their relatives and friends. Bring along any photos or memorabilia you might like to share.
