The Arcadius Business Center is a skyscraper featured in Grand Theft Auto V and located in Downtown Los Santos, San Andreas. This building has a characteristic circular form with interconnected towers. It features a helipad on its roof. The building is just right next to the Union Depository, connected by a bridge. In the heist mission The Big Score, if players choose the obvious way to steal the gold, then Michael and Franklin with the gumman will have to fight their way through the building to the getaway car stopped in its underground parking lot after the gold is taken by Trevor.
- There is an inconsistency between the design in GTA V and the real-life building; the Westin Bonaventure Hotel building has 4 cylindrical towers, whereas the Arcadius Business Center only has 3.
- The triangular logo on the building is identical to the player icon on the minimap in the HD Universe.
- This is the building where Franklin covers Michael from in the mission Three's Company.
