Built in 1858, the John Wornall House is one of the few antebellum homes remaining in Kansas City. It was built by its namesake, John Wornall, who had it designed in the Greek Revival style. The two-story brick structure was built with thick walls and is today furnished with period furniture to represent what a prosperous, pre-Civil War household looked like. Wornall made his living as a farmer. The house stood on a 500 acre property and slaves tended to the crops and household tasks. The house is also significant for its association with the Civil War Battle of Westport, which took place in October 23, 1864 and resulted in a Union victory. The house was used by the Union and Confederates as a field hospital. Given its age and significance, the house was added to the National Register of Historic Places in 1969.
