We’ve seen several scenes shot on top of a roof in downtown Atlanta. Most notably is the scene where Merle Dixon is handcuffed to a pipe on the roof and later missing when Rick, Daryl, Glenn, and T-Dog come back to rescue him.
Unfortunately for photo takers, the rooftop used in these scenes is the roof of the Norfolk Southern building mentioned several times before. Since we don’t have access to that rooftop, I’ll pass along the Google maps location here.
Knowing where this rooftop is located takes creates a bit of vertigo because it’s on a building on the opposite end of the street from where the loading dock rescue and zombie walk scenes were filmed. The easiest way to think of it is Rick and Glenn were actually walking toward this building when in the show, and as seen through Morales’ binoculars, it appeared they were walking away from it.
