The main feature on the property is the ca. 1790 Georgian mansion that was the home of the Croghan family and gathering place for George Rogers Clark, Lewis and Clark, and U.S. Presidents. In addition to the mansion there is the Visitors Center that houses a gift shop, museum and meeting space.

Dozens of African Americans were enslaved at Locust House by the Croghans between 1790 and 1849. At the peak of the farm's operations in 1820, more than 40 enslaved people labored there.

The site was founded in 1790 by William Croghan and his wife Lucy Clark Croghan. The house and outbuildings were built by enslaved African Americans. Enslaved people also planted and harvested the crops, cooked the meals, made the family's clothing, washed their laundry, and were caregivers for the Croghan children.^[4]

Lucy was the sister of Brigadier General George Rogers Clark, former surveying partner of William Croghan and William Clark of the Lewis and Clark Expedition. At its peak, the Locust Grove estate was nearly 700 acres (280 ha) in size, and a small fraction of Croghan's extensive landholdings, which exceeded 53,000 acres (210 km²) at his death in 1822.^[1]

Tracing their way back from the Pacific Ocean, on November 8, 1806, Meriwether Lewis and William Clark arrived at Locust Grove to a homecoming where Lucy Clark Croghan and her family welcomed them back from their journey. Locust Grove became the only residence still in existence west of the Appalachian Mountains to have sheltered Lewis and Clark. In the Fall of 2006, Locust Grove commemorated the 200th anniversary of Lewis and Clark's return.

George Rogers Clark lived at the site in the final years of his life, from 1809 to 1818.

The property was adjacent to Springfield, the home of Colonel Richard Taylor and his son, future U.S. President Zachary Taylor.^[5]

Following the death of William Croghan, the estate passed to John C. Croghan, notable for his purchase of Mammoth Cave in 1838.

In the winter of 1844, the enslaved African-American Stephen Bishop produced a map of Mammoth Cave. His map was published in 1845 and remained the most complete and accurate map of the period until modern survey techniques were applied in 1908. A significant epilogue to Bishop's story occurred in 1972, when a long-sought route connecting the caves of Flint Ridge and Mammoth Cave Ridge was discovered in an area which Bishop had mapped, but which had in the interim been almost completely flooded by the construction of a dam on the surface nearby: the area of the 20th Century connection route is shown on Bishop's 19th century map.

It was declared a National Historic Landmark in 1986, as one of the few surviving residences associated with George Rogers Clark.^[1]^[3]
