A fire has broken out at Luckington Manor in Wiltshire.
10 fire engines from Malmesbury, Chippenham, Tetbury, Corsham, Westleigh in Swindon, Cricklade, Melksham, Calne, Dursley and Bradford on Avon are currently at the Grade II listed building.
Eyewitnesses say the roof of the building has collapsed, but there are no reports of any injuries.
Police have closed all roads around the manor, which is owned by the family of a sheikh who died last year.
Luckington Manor is a three storey building, measuring approximately 100m by 30m.
Wiltshire Fire & Rescue say the fire has so far caused severe damage to the first floor and about 30% of the property.
