California Architect Paul Murdoch won the competition to design the Flight 93 Memorial.
"There's a serenity to this place, which has to do with its open, rolling hills quality," Murdoch says.
The memorial will be using all 2,200 acres - a space twice as large as Manhattan's Central Park. Eventually, there will be a 93-foot tower with wind chimes, visible from the road approaching the site. A white marble wall - inscribed with the victims' names - stands along the flight path.
"I'd like a certain sense of reverence and awe here. We hope that everybody takes away whatever they need to," Murdoch says.
