Obama walked quietly through an expansive hall with former New York Mayor Michael Bloomberg, with the first lady, former President Bill Clinton and former Secretary of State Hillary Rodham Clinton following behind them.
Obama was set to speak at the dedication ceremony later today, with hundreds of dignitaries and Sept 11 victims' relatives, survivors and rescuers there to view the museum built to commemorate the 2001 terrorist attack, as well as the 1993 World Trade Center bombing. The museum opens to the public May 21.
By turns chilling and heartbreaking, the ground zero museum leads people on an unsettling journey through the terrorist attacks, with forays into their lead up and legacy.
There are scenes of horror, including videos of the skyscrapers collapsing and people falling from them. But there also are symbols of heroism, ranging from damaged fire trucks to the wristwatch of one of the airline passengers who confronted the hijackers.
The museum and memorial plaza above, which opened in 2011, were built for 700 million USD in donations and tax dollars. Work on the museum was marked by construction problems, financial squabbles and disputes over its content and the appropriate way to honour the dead, but its leaders see it as a monument to unity and resilience.
And its opening is prompting reflection from presidents and the everyday people whose lives were changed by the attacks. Former President George W Bush issued a statement yesterday saying the museum "will help ensure that our nation remembers the lessons of Sept 11."
