Let the winner of the memorial competition— the only open competition held so far—build his or her winning entry in a space of public assembly, not in the midst of a clutch of slick office towers. Let those who are so eager to build do so on the perimeter of the site, or in Midtown South, or in Queens or Brooklyn or the Bronx. Let us have a wonderful hub of transportation—the means of bringing people together—under and near Ground Zero. Let cultural institutions gather around the site, as they do around Central Park. But stop the demeaning arrogance of business-as-usual and the construction of an architectural zoo on this hallowed ground.
