Ultima Tower

Previously located in New New York, the now-destroyed Ultima Tower was a supertall skyscraper with a total height of 3,218 metres (10,558 ft).
While it's proposer Eugene Tsui only ever intended it to be a hypothetical, on December 25th 666 JJ, the Great Plink swept through and instantly constructed this great monolith smack-dab in the center of New New York.
