The ground is officially a mass grave and out of the 3000 people who perished only physical evidence of 1100 or so have been recovered. What ever they do it must incorporate some sort of memorial. TBops idea of an arch is a good one - If they created something huge incorporating an Arch that was also offices and had gardens of rememberence under it they would be gettingthe best of both worlds. They could go for something along the lines of the arch at La Defense in Paris but even bigger.
you say its a mass grave, but every speck of the towers was removed to another site for examination so surely those who not found will have their grave on the examination site not at the site of their murder.
