The '''Sentinel Wall''' is a massive wall built by the [[Sentinels]] surrounding the [[Quarantine Zone]] around the [[Library]] of [[Installation 05]] to keep the [[Flood]] from spreading.<ref>''[[Halo 2]]''</ref>

==Background==
===History===
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 [[Enforcer]]s keep the Flood contained, while [[Constructor]]s keep repairing the damage that the Flood inflict on the wall. It is possible that there is constant battle in the Quarantine Zone, as in the level of the same name, Flood and Sentinels are seen in many instances fighting one another. In addition to the massive physical wall, the Sentinel Wall also contained an energy barrier known as [[Containment Shield]].

===[[Battle of Installation 05]]===
Despite the efforts of the robotic keepers, the Flood were released when the [[The Arbiter (character)|Arbiter]] penetrated the defenses and deactivated the containment shield around the wall. It is unknown if such a structure exists on the other Halo installations. 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. It is possible that this is what allowed Flood to capture Covenant craft and attempt to use them to escape Halo, as seen in ''[[Halo: Ghosts of Onyx]]''.

===[[Battle of the Ark]]===
[[File:Ark_wall_1.jpg|thumb|right|The wall structure on The Ark.]]
When the UNSC forces landed on the Ark, they were to secure a landing zone for the ''Forward Unto Dawn'' to land. Unfortunately, the teams mounted up near a crashed Pelican, pushed through Covenant Loyalist forces but found the Sentinel Wall. The teams regroup at the Sentinel wall after saving the [[Sentinels]] from the Covenant Loyalists. After finding the path to the landing zone, the UNSC teams and the Sentinels join forces and fight their way through the [http://halo.wikia.com/wiki/Covenant_Empire Covenant] Loyalists guarding the entrance. The Sentinels had another task so they fly over a part of the wall to help defend it. After the ''Forward Unto Dawn'' landed and deployed a convoy of 3 Scorpion tanks and a Warthog, [http://halo.wikia.com/wiki/Miranda_Keyes Keyes] had a plan to go through the wall instead of over it. So the UNSC forces returned to the Sentinel wall and found a way through it, the [[Master Chief]] goes into an above entrance himself as [[Guilty Spark]] opens the doors for him and finds a switch activating a Light Bridge in which the convoy proceeds in through a tunnel, [[Constructors]] can be seen flying around a generator type object and seem to be repairing it while Sentinels fly around and guard them. It is known that the Sentinel wall is part of the [http://halo.wikia.com/wiki/Silent_Cartographer Cartographer building] because somewhere near the canyons half of the building can be seen forming from the Sentinel wall.

*Sentinel Walls are means of containment if primary measures fail.
*A section of the ''Sentinel Wall'' is clearly visible on the ''[[Halo 2]]'' Campaign levels [[Installation 05|Delta Halo]] and [[Regret (Level)|Regret]], as well as Multiplayer maps [[Containment (Level)|Containment]] and [[Isolation (Level)|Isolation]].
*Complying with the above statement, the Sentinel Wall can be visible and seen ''beyond'' the [[Prophet of Regret]]'s Forerunner Temple on the level [[Regret (Level)|Regret]], denoting its massive structure and size.
*A small sentinel wall surrounds the Halo 3 multiplayer map [[Isolation (Level)|Isolation]].
*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 array on [[Installation 04]].

-{{Main|Battle of Installation 05}}
-At some point, a containment failure on Installation 05 led to a [[Flood]] outbreak in the region surrounding the Library. A series of defensive barriers were activated in order to confine the Flood;{{Ref/Book|Enc22|Page=346}} this presumably led to the sentinel wall's containment shield being activated. During the battle on Installation 05, [[Thel 'Vadam|the Arbiter]] was sent into the wall to deactivate the shields keeping the Flood in the quarantine Zone in order to allow other [[Covenant]] forces fly over the wall towards the Library.

On the level Regret, the sentinel wall can be visible and seen ''beyond'' the [[Prophet of Regret]]'s [[Temple (Installation 05)|Forerunner temple]], denoting its massive structure and size.
