Flames swept through a derelict sugar refinery in northern Colorado Wednesday night, local media report.
At about 6:30 p.m., witnesses reported smoke pouring from the collapsed and neglected building in Longmont. More than two dozen local firefighters rushed to the scene.
Before the firefighting could start, responders had to cut through a 10-foot-high fence covered in aluminum sheeting to gain access.
The refinery, formerly known as the Great Western Sugar Company, dates back to 1905 and remained in operation for 74 years, the Longmont Times-Call reports. A complex of brick buildings located on 40 acres, the refinery was the scene of major fires in 2016 and 2017.
No injuries were reported. However, firefighters fought the blaze for 3½ hours with no end in sight.
