At the Downtown (South) end of the World Trade Center site, next to the Deutsche Bank Building and the FDNY September 11th Memorial, is the "official" viewing platform.

Behind the viewing platform there is a constriction wall for the Deutsche Bank Building (which is being deconstructed), which is stenciled with typical "Post No Bills" signs.

As things go, visitors have used the white stenciled letters to write mini-memorials.
