Columbia Vertical City

The Columbia Vertical City, also known as Columbia Tower, RPL-PetroPatagonia Condotower and pejoratively the Cyberpunk Tower, is a proposed 500-floor skyscraper in Meliepully, Patagonia. It was announced in 2007 but construction never commenced, later the architects who planned the tower admitted it was a fantasy project and never actually intended to be built.

If built, the building would be 1,600 meters (1 mile) high, twice the height of the current tallest building in the world, the Burj Khalifa in Dubai, United Arab Emirates.

The building was derided by locals as being "too cyberpunk". The unfinished Columbia Vertical City became a backdrop in various Patagonian cyberpunk movies. The rights to the concept were awarded by the architects to Puerto Bilbao-based YouTuber Andrew Evans, who later used it as a skyscraper in the fictional city-state of Ninjablox City where much of his animations are set.
