Here's a Look at Some of the Heartbreaking Artifacts Inside the New 9/11 Museum

NEW YORK (TheBlaze/AP) — Sept. 11 artifacts never before seen by the public will be on display following the dedication of the National September 11 Memorial and Museum, offering a gut-wrenching view of some of the items recovered in the rubble and a look at how the 2001 terror attacks shaped history.

"It tells how in the aftermath of the attacks, our city, our nation and people across the world came together," former New York City Mayor Michael Bloomberg, the memorial foundation's chairman, said at a news conference Wednesday. "This museum, more than any history book, will keep that spirit of unity alive."

The museum was dedicated Thursday with President Barack Obama, Michelle Obama and former Secretary of State Hillary Clinton in attendance.

Here's a first look at some of the artifacts from the tragic event that are included in exhibits:

The museum harbors both personal possessions and artifacts that became public symbols of survival and loss. There is the battered "survivors' staircase" that hundreds used to escape the burning skyscrapers, the memento-covered last column removed during the ground zero cleanup and the cross-shaped steel beams that became an emblem of remembrance. (An atheists' group has sued, so far unsuccessfully, seeking to stop the display of the cross).

Portraits and profiles describe the nearly 3,000 people killed by the Sept. 11 attacks and the 1993 trade center bombing. Nearly 2,000 oral histories give voice to the memories of survivors, first responders, victims' relatives and others. In one, a mother remembers a birthday dinner at the trade center's Windows on the World restaurant the night before her daughter died at work at the towers.

The museum also looks at the lead-up to Sept. 11 and its legacy.

Watch WCBS-TV's report about the dedication:

The museum faced financing squabbles and construction challenges. Conflicts over its content underlined the sensitivity of memorializing the dead while honoring survivors and rescuers, of balancing the intimate with the international.

Holocaust and war memorials have confronted some of the same questions. But the 9/11 museum exemplifies the work it takes to "develop a museum program amidst this range of powerful feelings and differing individuals and issues that get raised," said Bruce Altshuler, the director of New York University's museum studies program. He isn't involved in the Sept. 11 museum.

Members of the museum's interfaith clergy advisory panel raised concerns about plans to show a documentary film about Al Qaeda that they said unfairly links Islam and terrorism. The museum has said the documentary is objective and its scholarship solid.

While some Sept. 11 victims' relatives have embraced the museum, others have denounced its $24 general-public ticket price as unseemly and its underground location as disrespectful, particularly because unidentified remains are being stored in a private repository there. Other victims' families see it as a fitting resting place.

The museum and the memorial plaza above it cost a total of $700 million to build. They will cost $60 million a year to run, more than Arlington National Cemetery and more than 15 times as much as the museum that memorializes the 1995 Oklahoma City bombing. Sept. 11 museum organizers have noted that security alone costs about $10 million a year.
