The property surrounding the mansion included the location of the first mound found to belong to the Adena culture<ref>[http://www.ohiohistorycentral.org/entry.php?rec=2411 Ohio History Central]</ref> and thus the Adena mansion is the namesake for the Adena people. The state coat of arms depicts the view of Mount Logan from the Adena property. The Adena Mansion is owned and operated by the Ohio History Connection and is open seasonally to visitors for a small fee.
==History== thumb|left|Mansion and outbuildings The stone mansion has historically accurate interiors, including furnishings. The grounds cover {{convert|300|acre|km2}} of the original {{convert|2000|acre|km2|adj=on}} estate. There is a garden area featuring kitchen herbs and heirloom vegetables, with some varieties available for purchase. A former overseer's house has also been restored and demonstrates life for German immigrants to the area.
A modern museum and education center features exhibits on the early European settlement of Ohio. Documents for indentured servants, other primary source materials and archeological finds are showcased.
Thomas Worthington recorded that he chose Adena as the name for his estate because it referred to "places remarkable for the delightfulness of their situation." The museum at Adena has an exhibit which claims Adena is based on a Hebrew word.{{Citation needed|date=March 2026}}
