The Opatrny Village Site is an ancient village site dating from AD 1000–1600. The site was inhabited by the Monongahela culture and is a contemporary with the Fort Ancient cultural way of life. The property was placed on the National Register on 1975-05-21.

The extent of the site has not been fully determined as the artifacts lie in occupational debris over 1.5 feet thick. The site has been used as a pasture and remains largely intact. The property was placed to protect the integrity of the site from a highway project.

Around 1980, an extensive excavation was carried out at Opatrny; the information that it yielded was seen as highly significant in understanding the ways that local cultures changed and developed their surrounding terrain.^{[3]: 367–368} Despite its location along U.S. Route 40, the village remains less disturbed by modern development than most surrounding terrain.^[2]
