What has happened to the World Trade Center Memorial? A year after being chosen, the design has been bloated, writes James Russell. “It was inevitable the planned memorial would grow to a disturbingly large size, once it was deemed that the towers’ footprints must be entirely preserved — for political, not design reasons, in response to pleas from some of the victims’ family members. In the past year, the proposed project has expanded into a vast commemorative complex; it threatens to become a grandiose paean to grief.”
