The Gordon Lee Mansion was originally the Gordon residence built by James Gordon, who began construction in 1840 and completed in 1847. The mansion and surrounding buildings are now used as a bed and breakfast as well as a restaurant and banquet center. Crawfish Spring, the main water supply for the early settlements, and later for the city of Chickamauga in the early to mid-20th century, is located on Cove Road just south of the main town and across the road from the Gordon Lee Mansion. The spring is no longer used as a water supply and has been converted into a park setting with picnic tables, a swing, and a gazebo. The Holland-Watson Veterans' Park was dedicated on May 27, 2002. It is named after two Chickamauga soldiers, Sgt. Eddie H. Holland and Cpl. Thomas A. "Tommy" Watson, who lost their lives during Vietnam. A Huey helicopter is mounted on a pedestal in the center of the walking track as a symbol of the war and those who fought and died for their country.
