Sentinel walls[1] are massive walls on Halo installations intended to serve as means of containment if primary measures fail in the event of a severe Flood outbreak. As their name suggests, the walls house numerous Sentinels to both repair the facility and keep the Flood from spreading beyond the wall. A Sentinel wall surrounded the Quarantine Zone around the Library of Installation 05 to keep the Flood from spreading.[2]
Background
The wall appears to have been designed to keep the outbreak of Flood around Delta Halo's Library contained within the Quarantine Zone. It is honeycombed with tunnels for the Sentinels to travel through. Sentinels and Enforcers keep the Flood contained, while Constructors keep repairing the damage that the Flood inflict on the wall. In addition to the massive physical wall, the Sentinel Wall also projected an energy barrier known as a Containment Shield.[2]
Battle of Installation 05

Despite the efforts of the robotic keepers, the Flood were released when the Arbiter penetrated the defenses and deactivated the containment shield around the wall. During the battle on Installation 05 the Arbiter was sent into the wall to deactivate the shields keeping the Flood in the Quarantine Zone in order to let other Covenant forces fly over the wall towards the Library.[2]
Trivia
- A section of the Sentinel Wall is clearly visible on the Halo 2 campaign levels Delta Halo and Regret, as well as the multiplayer map Containment. The Sentinel Wall can be visible and seen beyond the Prophet of Regret's Forerunner temple on the level Regret, denoting its massive structure and size.
- It is unknown whether the other Installations have this feature, as the player would have bypassed the wall due to the Monitor's use of the teleportation grid on Installation 04.
