Adena Mansion was built for Thomas Worthington by Benjamin Latrobe, and was completed in 1807. It is located on a hilltop west of downtown Chillicothe, Ohio, United States. The property surrounding the mansion included the location of the first mound found to belong to the Adena culture and thus the Adena mansion is the namesake for the Adena people. Adena Mansion is often open for visitors for a small fee.
The stone mansion has historically accurate interiors, including furnishings. The grounds cover 300 acres (1.2 km2) of the original 2,000-acre (8.1 km2) 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 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.
