From the top of One World Trade Center, it really does seem as if you can "see forever."

"See forever" is the motto of the center's new observatory that opens May 29, offering spectacular views stretching 50 miles past the Manhattan skyline to the Atlantic Ocean.

But even when the 1,776-foot building disappears into the clouds, there are still plenty of high-tech displays that reflect the optimism of a building and a city that rose from the ruins of the nation's deadliest terror attack.

In the elevator, a time-lapse panorama unfolds five centuries of New York history.

High in the sky, visuals and voices pull visitors into bustling daily life in New York City.

And for those afraid of heights, visitors can walk on video screens that show the dizzying view.
