This painting in Downtown Columbia commemorates the first Methodist Episcopal Church of Columbia from 1819. This is one of seven small murals around the Nelson House Hotel a block north of the Columbia, TN town square. They have been painted by local mural artist Bonnie Callewaert. Three of them are visible in a parking lot next to the historic hotel and the other four are behind the building. Other than Aesthetics, I can't find any info on why or when on these.
