Designers unveiled plans Tuesday for a portion of the September 11th Memorial and Museum at the World Trade Center site, just days ahead of the seventh anniversary of the terrorist attacks.

The $80 million glass pavilion features steel siding meant to resemble the twin towers and sits between two memorial pools, surrounded by a grove of trees.

"We want people to feel an unusual experience. We want them to know they're in a very special place and that there's a history as well as a future to this location," said architect Craig Dykers.

The Norway-based designers, working in firm Snohetta, have also incorporated original pieces of the fallen World Trade Center, like the two trident shaped pieces of steel.

"One obligation we take very seriously is the fact that we have to use artifacts that are genuine from the site to tell the story of 9/11," explained Joe Daniels, president of the September 11th Memorial and Museum. "Those artifacts can be actual pieces of the building, like the trident. They can be oral histories from survivors. They can be the small-scale artifacts that were recovered on the site. But I think people are most engaged when they hear from the authentic source."

The building also provides a private meeting space for victims family members.

The atrium lobby inside the pavilion will offer access to and from the memorial museum, which will contain both artifacts and oral histories of the attacks. There will also be an auditorium for educational programming, a café and rest area.

"I believe we're creating a space where people can find an alternative experience," said Dykers. "They won't necessarily be focused on the memorial, they won't necessarily be focused on the commercial venues around. It's just a place where you can get together, relax and collect your thoughts."

The lobby will also allow daylight to stream into the museum's lower levels, where visitors can reach the main exhibit at bedrock within the original tower footprints.

Lower Manhattan officials say all of the funding for the memorial museum pavilion is already in place, and now the facility just needs to be built.

The target date for completion of the Memorial and Museum is September 11, 2011, in time for the 10th anniversary of the attacks.

Meanwhile, a memorial was unveiled today at Boston's Logan International Airport honoring the victims.

Inside the glass exhibit, twin towers mark the time American Airlines flight 11, and United Airlines flight 175, took off from Logan before crashing into the World Trade Center.

Etched into the glass are the 148 names of the passengers and crew aboard both flights.
