A national historic landmark, the site was established by William Clark’s brother-in-law and sister, William and Lucy Clark Croghan, in 1790. Lewis and Clark and the Clark family celebrated the captains’ return with a party at Locust Grove on November 8, 1806. This gives Locust Grove the important distinction of being the only known surviving Lewis and Clark related structure west of the Appalachians. George Rogers Clark spent the last nine years of his life here, from 1809 until his death in 1818. The site also was home to numerous enslaved African Americans who lived and worked on the farm and contributed to its success. It is a certified site on the Lewis and Clark National Historic Trail.
