The two holes left from Buildings 1 and 2 of the pre-911 World Trade Center, figuratively or is it ostensibly, constitute the public area of the September 11 Memorial. Both are square, sunken “reflecting pools” into which water falls. Inside each an inner square hole appears to sink forever, deep enough that the base cannot be seen by even the tallest of visitors standing on tiptoe. Ironically the only location that affords a view into the bottomless mystery is the adjacent One World Trade Center, situated where the former WTC Building 7 stood, which I guess didn’t merit a memorial, the better to erase its memory. It would not surprise me if the fresh Eichmanns who will soon again populate the OWTC will be treated to an inside joke fitting for whichever of them chooses to stare into the abyss. At the base of the bottomless pools, printed in bold letters, shielded from errant-eyes by the post-911 no-fly zone, entrusted only to the exclusive fraternity of the top floor who know it already, read the words “WE DI DI T!”
