The Corona Tower Mall is known city-wide as simply "The Mall."
The mall covers a total of 64 city blocks, 8 blocks by 8 blocks, minus the footprint of the actual Tower. It is a venue for concerts, shows, and other publicized events.
When an event is scheduled, a wall surrounding the mall rises out of the ground to a height of twelve feet to enclose the mall area. Nominally, anyone can purchase tickets to the well-publicized mall events, but in reality, they are always sold out to the public.
Events on the mall always take place in the evenings. No one in Bay City knows anyone who has been able to procure a ticket. Everyone wants to.
We discover Corona Mall in Book 1 of The Human-Hybrid Project, Shattered by Glass.
