The Sears/Willis Tower in Chicago that is constructed in a Minecraft Creative server back in February. This only has the skydeck and cafe/gift shop but I will upload a video that has some more places inside.

The windows are vertical because it was easier to make than horizontal.

Photo is from a website called "5 magazine"

The inside isn't supposed to look like the real thing.

Watch the video to see the Sears tower.

Server name won't be mentioned to prevent griefers.
