A cornerstone removed

New York City

Nearly two years after it was dedicated, the cornerstone of the Freedom Tower was removed last week from the site where the World Trade Center once stood. The 20-ton, 5.5-foot-tall stone was loaded onto a flatbed truck and returned to a Long Island stone yard for up to two years, where it will remain in a plexiglass case while construction goes forward. The move was necessitated when security concerns forced designers to shift the foundation of the tower 40 feet west of its original location.
