Presbyterian church in continuous operation since 1850 and the site of a winter encampment during the Trail of Tears. Only site certified by state of Illinois and Cherokee Nation.
Entering Union County, the Trail of Tears passed through Pleasant Grove and Mt. Pleasant to the site of the present-day Camp Ground Church. This was a common campground for travelers and it is likely that many of the detachments stopped and camped here and perhaps buried their dead near an existing small family cemetery. It is estimated that up to 6,000 may have camped at this site waiting to cross the Mississippi River.
