The Greenville Mausoleum is an imposing Egyptian Revival structure in Greenville, Ohio, United States. Built in 1913, this historic mausoleum is built of concrete covered with courses of limestone, resting on a foundation of granite and covered with a roof of ceramic tiles. Among its most distinctive elements are the marble pillars, topped with capitals of the Doric order, that line the main entrance. The main portion of the interior, built in a basilican style with multiple aisles, contains approximately four hundred concrete and marble crypts, and the building's wings house individual family crypts. It is lit by twelve clerestory windows under the roofline.
