Barrier tower
From Halopedia, the Halo wiki
A Barrier Tower[1][2] is a Forerunner shield-generation tower.
Three of them surrounded the Citadel on Installation 00, projecting an energy shield that denied access to the Citadel. They could be individually deactivated by means of a holographic control panel on their upper floors[3].
