The Crenshaw House (also known as the Crenshaw Mansion, Hickory Hill or, most commonly, The Old Slave House) is an historic former residence and alleged haunted house located in Equality Township, Gallatin County, Illinois. The house was constructed in the 1830s. It was the main residence of John Crenshaw, his wife, and their five children. In 2004, the National Park Service named the mansion as a "station" on the Reverse Underground Railroad to acknowledge Crenshaw's practice of kidnapping free blacks in Illinois and selling them in the Slave States.
