The Lemuel P. Grant Mansion is a historic house located on St. Paul Avenue between Broyles and Grant streets in the Grant Park neighborhood of Atlanta. It is one of only three antebellum houses in the city of Atlanta still standing in their original locations. It is also by far the closest to what were in the 1860s the Atlanta city limits. The mansion was owned by Lemuel P. Grant, Atlanta's quintessential railroad man as well as a major landowner and civic leaderafter. Grant donated the land for Grant Park, which was named for him.
The three-story, Italianate mansion was built in 1856. The house was constructed of buff stucco with 2-foot wide walls, 10-foot windows, nine fireplaces and a ballroom.
