Firefighters were called to tackle a fierce blaze which broke out in a log cabin at Braco Castle in Perthshire on Monday evening.
One crew from Dunblane and two from Auchterarder raced to the scene and found the building in question well alight after an initial 999 call was made at 6.51pm.
No-one was injured and no-one had been occupying the cabin – which measured around 18 metres by 15 metres – at the time when the fire broke out.
Crews used two hose reel jets and four breathing apparatus sets while fighting the fire.
A full investigation is likely to be carried out to ascertain the exact cause of the blaze.
