There are dozens of miles of tunnels beneath las vegas referred to as the "homeless tunnels."
Literally an undercity of people enslaved and tortured and preyed upon by the lovecraftian horror that is capital, all so this thing can exist looming above the city like a monument to some eldritch god, a spherical obolisk that almost defies perception.

I am very fun at parties, the last one I was at I started a very stimulating conversation about scientific socialism that lasted for hours even when I went to buy smokes and came back 15 minutes later people were carrying on.
