Above ground, the mounds become a spiritual center and political backdrop. The towers become meeting places and interim front-line headquarters for key players in the rebuilding effort. The walls tie the pieces together, and the Sphere provides the center point.
Below the mounds is where the transportation hubs were and a lot of that is already being rebuilt more or less as before. The mound-museum transportation and access system will blend right in with these efforts and in no time at all the key corner of the World Trade Center Memorial starts working again while at the same time providing for associated spiritual and emotional needs.
Woven into the transportation and support space under and alongside the mounds will be the underground viewing and remembrance space for portions of the retaining wall. This area will be among the most powerful spaces in the whole site, and will display the retaining wall as it should be - underground, as it was before, during and after the original Twin Towers.
