It’s also simple, moving, and serenely located on the pastoral waterfront lip of the north shore of Staten Island, overlooking New York harbor and the skyline where the twin towers once soared. Called Postcards… the memorial consists of a pair of 40-foot-tall sweeping white wings, fashioned from steel and fiberglass, into which the names and silhouetted likenesses of 271 Staten Island
residents who perished in the attack have been chiseled. Located just west of the ferry terminal and a long fly ball’s distance from the Staten Island Yankees ballpark, the memorial rests on the edge of the new St. George Esplanade.
