The Tiara was a space station in equatorial geosynchronous orbit over Utgard, on the human colony Harvest.


The Tiara is described as two arcs separated by the carbon nano-fiber strands that made up the space elevators of Harvest. The beam work connecting the elevator strands to the arcs resembled delicate filigree. Six beveled titanium spars ran the length of the facility. Avery Johnson estimated the station was about 4 kilometers long and it's interior around 300 meters in diameter (13,200 and 990 feet, respectively).[1] It possessed some form of artificial gravity as well.


Constructed in 2468 when the Harvest colony was founded, it supported the seven space elevators servicing the colony's capital city of Utgard, and functioned as an orbital port for passenger and cargo transport, as well as the storage area for the data centers of the AI Sif, who was in charge of Harvest's shipping operations and maintaining the Tiara 's position.[1]

The Tiara was not present in 2502, but was fully functional by 2524. It, along with Sif, was destroyed in 2525 when Loki fired Harvest's mass driver from the surface of the planet, just before Harvest fell to the Covenant. The strands wrapped around Harvest, as per its rotation and the remnants of the Tiara fell into Harvest's atmosphere.[2] In a state of grief, Mack, Harvest's agricultural AI, used the JOTUNs to bury the elevator strands of the Tiara, protecting them from plasma fire as Harvest was glassed by the Covenant.[3] During the First Battle of Harvest, the Tiara was taken over by the Covenant, but was retaken by Sergeant Johnson and his militia. The Tiara was used to evacuate the population of Harvest in freighters, but the number 7 strand collapsed from the weight, but was rebalanced by Sif after Lighter Than Some repaired her.


  • Seven space elevators run from Harvest's ground to the Tiara. The number is a reference to Bungie's favorite number.
  • In the Halo 4 map Harvest, some of the computers in the centre structure mention the Tiara.
