CALVERT — A piece of Calvert’s history came crashing down Friday morning when a building dating back to 1890 collapsed along Main Street. The building at 501 Main St., near the corner of Main and Mitchell streets, collapsed around 8:30 a.m. August 21, sending bricks and debris across the property and forcing authorities to temporarily close a portion of Highway 6 through downtown Calvert. No injuries were reported. Robertson County Emergency Management responded to the scene while crews worked to clear the debris and secure the area. Photos from the collapse showed much of the building reduced to piles of brick and rubble. The loss is significant because the building had been part of downtown Calvert for more than 130 years. Archived real estate records list the building as having been constructed in 1890, a date that was also displayed across the top of its white-painted storefront. The approximately 2,600-square-foot building had most recently been used as a bar. A real estate listing for the property noted that the historic structure needed work. When the Calvert Historic District was nominated for the National Register of Historic Places in the 1970s, the property at 501 Main St. was identified as Calvert Arts & Crafts. Downtown Calvert contains one of the area’s most recognizable collections of late-1800s commercial buildings, many dating to the period when the railroad and cotton trade helped turn the community into a busy commercial center. Main Street became the heart of that growth, with brick storefronts replacing many of the town’s earlier wooden buildings. The collapse of 501 Main now leaves another opening in that historic streetscape. For generations, the building stood along one of Calvert’s busiest streets. By Friday afternoon, much of the 136-year-old structure was gone, leaving behind bricks, rubble and another missing piece of the city’s historic downtown.
