The new Canberra Rotary Peace Bell is being unveiled on Friday, with members of the public invited to ring it between 11am and 2pm on Saturday and Sunday.

The 350-kilo brass bell came from Japan. It is a replica of the peace bell at the United Nations HQ in New York.

Its design includes 103 coins from nations of the UN. It is the 23rd peace bell in the world.

The bell will usually be rung on World Peace Day on the third Tuesday in September each year. That date also coincides with the opening day of the United Nations General Assembly, and national and international days of remembrance and celebration.

The community is also invited to Friday's launch of the peace bell, housed in a specially-built pavilion at Canberra Nara Peace Park on the shores of Lake Burley Griffin.

The launch is 10.30am to noon Friday.

The Peace Bell project was initiated by Rotary in partnership with the World Peace Association. Rotary Canberra Burley Griffin took on the ambitious project of fundraising, coordinating the design with local firm Kasparek Architects and overseeing the build of the World Peace Bell Pavilion, by RAM Constructions.

Rotary Canberra Burley Griffin coordinator Michael Rabey said he hoped the bell was sounded loud and clear over the weekend.

"We think if hundreds and hundreds of people turn up over the weekend, it will send a clear message to the authorities to think very carefully before they commit our young men and women [to war]," he said.

The peace bell was a fitting achievement to mark the 90th anniversary of Rotary in Canberra.
