A raging fire at a farm in Lancaster on Saturday burned a barn to the ground and caused an estimated $1.2 million in damage, a fire official said.

Firefighters responded to Manny’s Dairy Farm on Brockelman Road shortly after 1 p.m., said Lancaster Deputy Fire Chief Michael Hanson. He said the blaze grew to be five alarms, and officials from about 23 towns helped douse the flames.
