Family members of victims, first responders and survivors gathered at what once was the site of the World Trade Center, joining President Obama and political dignitaries to dedicate the 9-11 memorial museum.
The president said here we can see the faces of the nearly 3000 innocent victims of the terror attacks hear their voices.
“Here we tell their story - so that generation yet unborn so that generations yet unborn will never forget,” said Obama.
A decade in the making the museum is vivid and at times gut wrenching journey through that day that changed the nation.
It’s seven stories underground all the way to the bedrock that supported the towers built around these stairs used by hundreds to escape the horror above.
Visitors can walk through the day minute by minute.
They can hear the voices of regular people from 48 countries, sharing their memories.
There is 500 hours of video and film, 23,000 still photographs and 10,000 powerful and poignant artifacts including a melted rolodex, a phone and this watch found in the field in Shanksville, Pennsylvania that belonged to Todd Beamer, a hero on Flight 93.
For the next six days, survivors, families of victims and rescue workers will have a chance to see the displays before the museum opens to the public next week.
