monument, NRHP - National Register of Historic Places, boundary marker

This is one of 40 boundary markers that were placed from 1791 to 1792 as part of a survey to delineate the boundaries of what would become the District of Columbia. Four of the original markers have been destroyed, and 12 of them are actually in the state of Virginia; part of D.C. originally extended into Virginia, but the Potomac River was designated the dividing line between Virginia and the District in 1846. All 36 of the surviving stones are listed on the National Register of Historic Places (NRHP)
