FRYEBURG, Maine (AP) — A massive fire has destroyed two buildings and damaged several others at a historic fairground in Maine.

Officials say the fire started inside a sheep barn and spread to the cattle shed Tuesday night at the Fryeburg Fairgrounds, home to the state's largest agricultural faire.

Both buildings burned to the ground, and fair officials say six other buildings are damaged.

No animals were inside the structures at the time of the fire, and no injuries were reported.

At least 20 fire departments responded to the blaze, and fire officials are now working to determine the cause of the fire.

Fair officials say the 160-year-old fair will still happen in the fall, even if they have to resort to using tents.
