The Coliseum at Origin
The largest multi-purpose indoor venue ever built — suspended in the Void.
"Stadium" is wrong. The Coliseum hosts NFL, soccer, basketball, baseball, hockey, boxing, MMA, gymnastics, concerts, conventions, ceremonies, esports finals, world championships — and whatever humanity invents next.
It is named for the Roman Colosseum: the original multi-purpose mega-venue. Origin's Coliseum is its 21st-century successor at vertical-city scale.
Hung between Tier 1 and Tier 2
The Coliseum is suspended in the Void at the lower skybridge tiers — between floor 100 and floor 200. Tied to the structural skybridges that already span the formation, it does not require new primary structure to hang. The skybridges that hold up the Spire also hold up the Coliseum.
Bigger than any concert venue on Earth
NFL configuration: 70,000–100,000 seats. Concert configuration: significantly more — the Coliseum's geometry is a bowl with seating wrapping nearly all the way around, more like a theater-in-the-round than a traditional stadium. Maximum concert capacity targets 150,000+.
Look up through the Void
From the field, the sightline above the upper deck is 1.4 miles of open vertical sky to the Apex. There has never been a venue where, from your seat, you can see weather above you and bedrock below you in the same glance.
Acoustic, mechanical, structural
The Coliseum is suspended — not built on grade — which transforms its acoustic problem (echo paths up the Void) and its mechanical problem (HVAC routing through skybridge structure). Solvable at this scale; novel in execution.
Origin's own franchises
Origin can support its own NFL/NBA/MLB-class franchises. NeuraWeb-owned teams play in the Coliseum, fill it natively rather than renting it, and turn the venue into self-sustaining year-round programming. Pending strategic decision on franchise acquisition timing.
