The twin towers being built in full glory had remained in isolation as a remembrance of the ill-fated day, but now the site is open to public and is gradually reconnecting to the city. Today being the 13th anniversary of the incident, politicians, families and other dignitaries will gather here to mark it in sobriety. The program also includes recitation of the 3,000 victims' names who lost their lives then.
These moments of silence will also be observed in Washington, where a hijacked plane plowed into the Pentagon, and the field in Shanksville, Pennsylvania, where another hijacked plane crashed.
The ceremony today is important in more than one way. It is also the first commemoration since the opening of the 9/11 museum and the adjoining repository for unidentified human remains at the site. Moreover, the National Park Service said,"the Congressional Gold Medal, the nation's highest civilian award, honouring the passengers and crew who were aboard that flight, will go on public display for the first time."
Michael Frazier, a museum spokesman said,"For the first time this year, because the museum opened in May, family members will be able to visit the museum as part of the commemoration."
Meanwhile, amid the huge uproar created by the beheading of two hostages and Obama's speech of "finishing the ISIS", two of the new skyscrapers built around the site of the fallen twin towers are now open. However, 1 World Trade Centre, the tallest skyscraper in the Western hemisphere, is due to open later this year.
