During the War of 1812, the U.S. Army built a two-story blockhouse on a nearby hill as one of a series of structures erected along the Greenville Treaty line to guard against Native Americans who supported the British during the conflict. After the war, Daniel Markley, one of Green Camp Township's first white inhabitants, settled near the blockhouse. In 1963, graves of twenty-five prehistoric Glacial Kame Indians, six white settlers, seventeen War of 1812 veterans, and eight others were discovered near the site, and the bodies were later removed and reinterred at Green Camp Cemetery. An abandoned right-of-way of the Erie Railroad, Dayton line, also passes through the area, where prairie grasses that once dominated parts of Marion County can still be found.
