Statement of Significance (as of designation - July 19, 1964):
Occupied intermittently from about 2000 BC, this site, on a low sandy Potomac River terrace opposite Mount Vernon, is remarkable for its variety and concentration of human occupation sites. Accokeek included a palisaded village that was occupied from ca. A.D. 1300 to ca. 1630. The site has been used by archeologists to define a culture-history sequence in prehistoric archeology for the Mid-Atlantic region.
