Firefighters battled an early morning warehouse fire in Fairmont this weekend. About 4:00 Sunday morning, the former "Swiss Piedmont Knitting Mill" went up in flames. Several fire departments from across the area responded to the corner of Walnut and Center streets, but not in time to save the abandoned warehouse. The fire rekindled later that afternoon, but was quickly brought under control. No was injured in either fire, and the cause of the original blaze is under investigation.
