Firefighters have tackled a major blaze at a derelict north-east mansion.
Four fire engines were called to tackle the large fire at Tertowie House in Kinnellar on Sunday afternoon.
Up to 44 crew were at the scene at the height of the blaze. Crew spent around four hours dealing with the fire which broke out at the former residential school at around 5.25pm.
Two fire engines remain at the scene on Monday morning ensuring the fire is fully extinguished.
A Grampian Fire and Rescue spokesman said one wing of the building was "particularly badly" damaged, but the rest of the house was "pretty much intact".
An investigation into the cause of the blaze will be launched one the fire has been fully extinguished and the building is made safe.
It not thought that there was anyone in the building at the time of the fire.
Tertowie House is a B-listed 16th century mansion which was bought by Aberdeen City Council in 1944 and also used by Aberdeen College.
It is thought to have been empty for around a decade.
A nuclear bunker was built under the gym in 1962, accessed through a steel blast door and a 40ft concrete corridor.
The Grampian Regional Council Emergency Centre was opened there in 1962.
