The Lanier Mansion State Historic Site preserves the former home of James Franklin Doughty Lanier (1800-1881), bank president and railroad promoter. The site presents information on both Lanier and life during the 19th century. The structure itself was completed in 1844, and is Greek Revival in style. The grounds include replanted heritage gardens, reflecting the home's Post-Civil War landscaping.

The site offers guided tours, educational outreach programs, heritage gardens with historic plant varieties, and summer camps. Reservations are required for group tours and outreach programs.
