'''Sentinel walls'''{{Citation needed}} are massive walls on [[Halo Array|Halo installations]] intended to serve as means of containment if primary measures fail in the event of a severe [[The Flood|Flood]] outbreak. As their name suggests, the walls house numerous [[Sentinel]]s 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.<ref name="icon">'''[[Halo 2]]''', campaign level ''[[Sacred Icon]]''</ref>

==Background==
== 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 [[Sentinel]]s to travel through. Sentinels and [[Enforcer]]s keep the Flood contained, while [[Constructor]]s 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]].<ref name="icon"/>

Despite the efforts of the robotic keepers, the Flood were released when [[Thel 'Vadam|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.<ref name="icon"/>

[[Installation 00]] contained a similar, though far smaller, security wall structure near its [[Cartographer]]. Inside the wall was a deep chasm and an [[energy bridge]] allowing passage over it. A [[terminal]] was located within the wall near the activation switch for the energy bridge.<ref>'''Halo 3''', campaign level ''[[The Ark]]''</ref>

When the UNSC forces landed on the Ark during the [[Battle of Installation 00]], they were to secure a landing zone for the {{UNSCShip|Forward Unto Dawn}} to land. The ground teams pushed through Covenant loyalist forces but were prevented access to the Cartographer by the wall. After the ''Forward Unto Dawn'' landed nearby and deployed a convoy of multiple vehicles, [[Miranda Keyes|Commander Keyes]] suggested they go through the wall. The UNSC forces returned to the wall and with the assistance of [[343 Guilty Spark]], successfully passed through.

==Trivia==
== Trivia ==
*A section of the Sentinel Wall is clearly visible on the ''[[Halo 2]]'' campaign levels [[Delta Halo (level)|Delta Halo]] and [[Regret (level)|Regret]], as well as the multiplayer map [[Containment]]. The Sentinel Wall can be visible and seen ''beyond'' the [[Prophet of Regret]]'s [[Temple (Installation 05)|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]].
