The Atlanta History Center comprises a decent sized museum building, a log cabin, a farm, and the Swan House on site. It also includes the Margaret Mitchell house out in Midtown. The museum exhibits are really well curated and unlike other period homes you are encouraged to interact with many of the historical objects in the outbuildings. There are also volunteers on the main property dressed and acting in period accurate way. A pretty nice little historical site.
