Firefighters battled a fire at the old Payless Shoe Store on Highway 76 in Marion.
Captain Jackie Yates said a passerby saw flames coming from the tip of the building and called 911.
He added crews were able to get the fire contained and under control.
Marion police blocked a portion of Highway 76 as crews fought the fire.
We're told the building was under renovation to house a law firm.
Yates said a cause has yet to be determined.
While the fire appears to be accidental, because of the extent of the damage they may never know what started it.
A massive fire destroyed the IGA Tuesday morning on Main Street in Marion.
