That isn't even close to being the ugliest building in the world. A giant hotel and restaurant complex in a country with no food, tourists, or functioning economy, may make it the most pointless building, but not the ugliest.
Now the State of Illinois building, (sometimes known as the UFO of LaSalle street) constructed by the only government on earth more corrupt than the North Koreans, boasts some real ugly. It also has heat, that works sometimes, AC that works in the winter, elevators that shake the whole building, and an atrium that flooded.
Or if we are going for Chicago ugly how about the new Soldier Field. This Close encounters of the Roman Coliseum can only be designed by a committee of monkeys, the built by the Chicago political machine.
Ugliest building in Chicago. Makes the Daley Center look charming.
BTW: Am I the only one who thinks that City Hall in said city looks like a block fortress with it's back turned to the city on all sides?
