The '''Ultima Tower''' was a [[Proposed tall buildings and structures|hypothetical supertall]] [[skyscraper]], conceptualized and designed by American architect [[Eugene Tsui]] in 1991. It has been envisioned to be built in [[San Francisco, California]]<ref>{{cite web|url=http://listverse.com/2008/09/25/10-fascinating-buildings-never-built/|title=10 Fascinating Buildings Never Built|author=Blogball |date=25 September 2008|website=listverse.com}}</ref> and could accommodate up to one million people. With a total height of {{convert|3218|m|ft}}, the tower would be {{convert|2|mile|spell=in}} tall, and comprise 500 stories if built.
