The Harmon tower footprint
The Harmon tower was originally planned as part of the massive, modern CityCenter complex, where you can find the ARIA, Mandarin Oriental, and Shops at Crystals. However, there were construction flaws, and the high-rise was capped at just 28 floors, instead of the original 49. The building was finished, but ruled unsafe, and the public was never allowed inside. Years of litigation followed while the Harmon tower became the world's most expensive billboard -- with an advertisement for the "Zarkana" Cirque show wrapped around it. Finally, with the legal matters settled, the tower was demolished -- very slowly, piece by piece -- instead of with a fun, classic Vegas-style implosion. It soon became a hole in the ground, and today it's just an ugly patch of concrete with a fence around it.
