Tredegar House workshop fire probe
An investigation is being held after a fire at a building near National Trust-run historic Tredegar House, Newport.
South Wales Fire and Rescue Service was called to the workshops at Pencarn Way, Newport, on Saturday at about 21:00 GMT.
The fire service said the 17th-Century mansion was not affected by the blaze.
The National Trust said the house and grounds would open as normal on Sunday for a Christmas event. It is not yet known what caused the fire.
On Friday, Prince Charles visited the mansion where he met school children and charity workers.
