A beacon will be lit at Shire Hall on Thursday 21 April 2016 to celebrate the Queen's 90th birthday.
So far over 250 birthday beacons are planned throughout the United Kingdom to mark the special day with organisations including town and parish councils, local authorities, youth groups and heritage sites taking part.
Cambridgeshire communities and organisations are also gearing up to celebrate the occasion, with plans for birthday card competitions, tea parties and exhibitions already in the pipeline.
Exact timing and details of the Shire Hall beacon will be announced closer to the time.
County Councillor Sebastian Kindersley, Chairman of Cambridgeshire County Council, said: "We are delighted to be taking part in the national beacon ceremonies to mark the Queen's 90th Birthday. It will be a day of real celebration and the events that take place can help foster a wonderful sense of community spirit, bringing together people old and young."
