This is a replica of the Willis (Sears) Tower, in Chicago, IL. It is 1/2 the size of the actual building. I had originally planned it to be full size, but was unable to because of world limits. As of this post, the tower itself is finished. However, I may add the inside of the tubes. There are no floors, because each story is two blocks. You can download the map for free if you want. Feel free to burn it down, blow it up, or do whatever you please.
...If you want to know why there is a couple craters, well... I was... Experimenting with redstone... and some TNT. There is a door to go inside, as well as a small, broken piston elevator.
