The September 11 Memorial on Staten Island was built in 2004 and remembers the 275 borough residents who were killed in the September 11 attacks and 1993 World Trade Center bombing. The design is the work of New York architect Masayuki Sono and is called Postcards after the two 30-foot pillars that are lined with plaques bearing the name and birthdate of those who perished in the attacks, including the place of work of those who died on September 11. The two structures frame the space on the skyline where the original World Trade Center towers once stood.
