Now a new exhibit is celebrating the 100th anniversary of the so-called Cathedral of Commerce, located at 233 Broadway.

"The Woolworth Building at 100" exhibit at the Skyscraper Museum in Manhattan is highlighting the Woolworth building's former glory as the world's tallest office building.

The display includes some of the original architectural drawings.

The original plans did not call for building the world's tallest office tower, but the museum's director says the design just kept on growing.

"And then when they knew they could get taller than the Singer Building, which was 625 feet, then they stretched it out to be the world's tallest tower, so his ambition grew along with his ego in order to make the Woolworth Building really broadcast to the world," said Skyscraper Museum director and curator Carol Willis.

While you can't just go in and tour the gothic revival skyscraper now, when it first opened in 1913 it was a big tourist attraction.

"This incredible view with the highest in the world where you looked out over New York Harbor and you see New York surging upwards and up the island. That was an incredible experience and people paid 50 cents at the time which is about $11 today in order to go up to the top of the building," Willis noted.

The exhibition runs through July 14. For more information, visit skyscraper.org.
