Can you create a small atmosphere with giant walls?

Can you create an atmosphere on a celestial satellite by using giant walls? Perhaps assisted with some means of technology? In a story I am creating I want to create something different from the normal bubble structures you see in some syfy novels.

Edit: What if there was a form of centralized gravity? As if there was a device that centered gravity into one place, but not large enough for the whole planet and not as strong as earth gravity?
