ACT Chief Minister Katy Gallagher today unveiled a plaque to celebrate the 100th birthday of the Heritage Early Childhood Centre building at the ANU.

"Over the past 100 years the building has played an important part in Canberra's history, in many ways reflects the development of our city," the Chief Minister said.

The birthday celebrations, was attended by past and present families who attended the Centre, and included the burial of a time capsule, Aboriginal story-telling, a presentation by local historian Allen Mewer, and the cutting of a special birthday cake. Children dressed in multicultural costume in recognition of the diverse cultures of those that attend the pre-school.

"The building is a lasting reminder of the ACT's rich heritage and it was great to take part in today's celebrations, recognising the fascinating history of this wonderful old building," the Chief Minister said.

The building is believed to be the fifth oldest in Canberra, dating from the very earliest days of Canberra. Over its 100 years, the building, once known as the Bachelor's Quarters, has served many purposes.

It was initially a hostel for staff from the Survey Office, later housed Navy personnel during World War II, and was home to thousands of public servants from 1946 to 1960. From 1960 onwards it was ANU student accommodation, when it was known as Lennox House. The building has been used for campus childcare since 1979 and became the Heritage Early Childhood Centre in 1995.

"The 100th birthday of the Centre also reminds us that our city turns 100 next year. With the preparations for our centenary celebrations almost complete, 2013 is sure to be an exciting and memorable year in the national capital," the Chief Minister concluded.
