Atlas Obscura is one of the largest, most well-known and most impeccably awesome archives of amazing places, foods and experiences in the world.
Here is their list of places to see in the Peach State, Georgia! Featuring such sites as: Central State Hospital, one of the largest ever mental hospitals which is now sitting abandoned; the CDC Museum, the sci-fi-esque reality of governmental disease management; and the Doll's Head Trail, a trail in Atlanta teeming with creepy doll's heads! How many of these cool sites have you been to?
Note: Some of these you cannot visit or see anymore, which have been marked with (Permanently Closed). So therefore, if you haven't already seen them, I don't know if you'll ever be able to completely finish this list.
Note 2: This is as of October 29, 2023. Sorry future people, there will definitely be more that can't be added.
