THE historic building at the heart of local government in North Yorkshire is set to celebrate a glorious centenary.

County Hall, in Northallerton, will turn 100 on Tuesday.

On Tuesday, July 29 1903, the then chairman of the old North Riding County Council, John Hutton MP, laid County Hall's foundation stone.

That ceremony will be remembered tomorrow when North Yorkshire County Council chairman Clifford Watson plants a tree in the hall grounds.

Coun Watson said: "It's a great honour for me as chairman to mark the centenary of County Hall in this way. This building has served as the backbone of local government in North Yorkshire for the past 100 years and I hope it will continue to do so for many years in the future."

County Hall was designed by York architect Walter Brierley, who described the red-brick building as "quiet and dignified English renaissance."

Three years after the foundation stone was laid, County Hall was completed. It cost £40,000, including the price of the land.
