Next slide…

Shows the enormous forces that bent and sheared this massive beam when the buildings collapsed

Next slide

Another photo of the last beam to be removed. It now stands on the ground floor of the museum

Next

On the ground floor of the museum, you can see what remains of the giant steel box beams which vertically supported one of the buildings. They were cut as part of the cleanup process since they go down to the bedrock.

Next picture

You see the box beams that go around a corner outlining where one of the towers stood. You can also see the slurry wall in the background.

Next slide…

A portion of one of the vertical beams that were visible at the base of the towers when standing.

Next slide

At street level, there are fountains now where the towers once stood.

Last slide

Another picture of one of the fountains. Part of the museum is directly below one of the fountains. When you cross over the box beam cutouts you actually enter underneath the space where one of the buildings once stood.
