A massive fire Tuesday evening destroyed the Swany White flour mill in Freeport, Minn. The entire structure collapsed as bystanders filled the streets of the Central Minnesota town to watch firefighters battle the flames, which could be seen for miles.

The owner of the century-old Swany White Flour Mill in Freeport tells the Star Tribune he has no plans to rebuild and that doing so would just be too expensive. The fire chief says investigators do not yet know the cause of the massive blaze that destroyed the iconic structure, but they have ruled out arson.

Investigators could not determine what caused the blaze that destroyed the landmark Swany White mill. The deputy state fire marshal said in a report released Tuesday that he could not conduct a thorough investigation because crews demolished the building to ensure the fire was out.

Facebook and Twitter have become places for some in central Minnesota to share their thoughts after a massive fire destroyed the Swany White flour mill last Tuesday. The St. Cloud Times reports the Freeport mill was family-owned and operated for more than 100 years. The mill won't be rebuilt, but the family might continue some of the Swany White products.

One firefighter was taken to a hospital Friday night at a three-alarm fire at a Minneapolis factory blaze that caused several explosions.

Firefighters sent 10 rigs to the blaze.

The fire broke out around 9 a.m. Friday.
