If you step into the elevators at One World Trade Center, you’ll briefly be transported through time. The elevator, which takes you to the observatory atop the 102nd floor, is flanked with nine high-definition monitors projecting realistic animations, giving you the illusion that you’re in a glass-walled elevator looking out at Manhattan below you.

For just 47 seconds, the history of New York City will unfold before your eyes. You’ll observe what once was a peaceful, marshy grassland transform into colonial New Amsterdam.

In the blink of an eye, windmills fade into giant skyscrapers. Eventually the New York we’re all familiar with comes into view. If you close your eyes for just a second, you might even miss the foreboding old 1 World Trade Center North Tower appear then quickly vanish from your very view.

The video of the ride, shared by Reddit user Deus_G in the Reddit Videos community, is a magnificent—and somewhat—jarring sight. Check it out below.

1500s-1600s

Your journey through time begins in the 1500s before New York City existed. The location of modern-day New York City, it seems, is still underground.

1600s-1800

In just 100 years, trees are replaced by a sprawling city. You’re witnessing the arrival of the Europeans and the changes—good and bad—that came with it.

1800s-1970s

The 20th century, however, marked the greatest changes. Towering buildings rise from the debris of a former civilization.

1970s-2001

For just four seconds, the old 1 World Trade Center stands proudly—a blink in time—before it fades from existence.

As one Reddit user reflects:

2001-Present Day

As far as including the North Tower on the ride? Legends Hospitality chairman David W. Checketts told the New York Times:

“The event is certainly a key part of history. We did not think you could ignore it. Having it appear in the year it did and disappear in the year it did was the respectful way of addressing the fact that it was part of the landscape,” he says. “There were strong opinions and emotional reactions all around.”
