COLUMBUS, Ohio (AP) " Step lightly between two facing mirrors at a first-of-its-kind museum honoring and celebrating the experiences of military veterans, and it takes your breath away. Behind and in front of you, as far as the eye can see, are folded flags.

You are standing midstream among the tidy triangles of past and future, the men and women who gave and will give their lives in service to the United States. The hall of flags is basked in sprays of color arranged on the windows, like stained glass, in the patterns of military service medals.

Developers of the $82 million, 53,000-square-foot National Veterans Museum and Memorial, which opens Saturday on Columbus' downtown riverfront, seek to inspire and educate visitors with this and other inventive interactive displays.

It shows military families cleaved and reunited, it visually visits young recruits aboard military vessels, it tells love stories, it mourns wrenching losses. All this is done through state-of-the-art interactive graphics, shifting photo images, documentary-style videos, oral history interviews and other engaging approaches.

General Colin Powell, the former secretary of state and chairman of the Joint Chiefs of Staff, serves as honorary chair of the museum's board of advisers. He'll deliver remarks during the weekend's grand opening festivities, which also include band performances and a motorcycle processional.

Amy Taylor, chief operating officer of the Columbus Downtown Development Corp., which spearheaded the effort, said it's neither a war memorial nor a traditional military museum. The goal is to show veterans' individual lives before, during and after they serve.

"It's a narrative journey and, while artifacts are here and we have them, they're only here to advance the story," Taylor said. "So it's not like, oh, I'm here to see the original 'Star-Spangled Banner' flag. No, you're here to learn a story and maybe an ice cream carton helps tells that story, or a drum helps tell that story."

The project, begun in December 2015, was the vision of Ohio native John Glenn, the late military hero, astronaut and U.S. senator who died in 2016. Taylor calls the museum a "labor of love" to Glenn and the veterans committee he convened to plan a site to memorialize "ordinary Americans doing extraordinary things."

The structure's sweeping concrete arches have drawn attention by designers, as well. Architectural Digest dubbed the museum one of the most anticipated buildings of 2018. Taylor said its lack of internal supporting columns is symbolic. "The strength comes from within, which we thought was appropriate for veterans," she said.

Congress also has taken note. In June, the facility was designated the nation's veterans memorial and museum.

Glenn is among dozens of veterans famous and obscure whose stories " at turns, poignant, intimate, or inspiring " are shared throughout the building.

Another is Tom Moe, a former state veterans services director under Republican Ohio Gov. John Kasich who spent more than five years as a prisoner of war in Korea.

Moe downplayed his own experience during a recent visit to the museum, instead focusing on his wife " who worked and raised their daughter alone while he was imprisoned " and on a "special friend" memorialized at the museum, the late Sen. John McCain.

"John and I lived next door to each other in Hanoi," he said. "Although we couldn't tap on the wall, there was a walkway between our rooms and some months, probably over a year, we spent waggling our fingers under the door and passing by a door and saying nice things, like, 'Cheer up,' and so forth."

The museum also remembers those who don't come home. A quiet, 2.5-acre grove whose waterfall is visible from the museum foyer is meant for reflection and remembrance.

Taylor said its developers hope the museum's location in the Midwest will allow many of the 21 million living veterans to make pilgrimages to the site. But she said the project also envisions frequent online updates and community involvement, as well as visits from school groups and civilians interested in learning about the veteran experience.
