Not to be outdone by Greenville's claim (see The Woodside Cotton Mill), this Columbia postcard of around 1915 describes the Olympia and Granby Cotton Mills: "Olympia Mill, the largest cotton mill under one roof in the world, occupies ten acres of floor space all under one roof, operates 104,000 spindles and 2,400 looms. The Granby Mill has about 60,000 spindles in operation. Other mills situated in what is known as the mill village, which has a population of 5,000, are the Palmetto, Richland, and Capital City."
