Here's some concept of a city in space. All the orbital objects are kept aligned towards the distant but highly radioactive neutron star stellar companion of the bright star to the right of the image. Each object has heavy shielding (both powered and physical) in this direction, to protect their delicate human occupants, with the rest of the object in the radiation shadow of that shielding. Many of the objects rotate independently, to give some level of artificial gravity, with the large ring rotating very slowly.
