Orbital Plate

A Great Crusade-era Orbital Plate visible in the sky above Terra

Orbital Plates are large space structures built by the Imperium. Essentially cities orbiting around their patron worlds, Orbital Plates can hold untold millions and often sport important industries, trading centers, and defenses.^[1][2]

Terra was home to some of the largest and most glorious Orbital Plates which were mostly constructed during the Dark Age of Technology. Most of these were destroyed over the Horus Heresy, either by Rogal Dorn decommissioning them for fears of their vulnerability for the coming Siege^[3] or by Horus' forces during the Siege itself.
