Paterson is known as the Silk City because it was once a giant center for making silk and other goods. It grew up around a powerful waterfall that provided energy for its factories.
You can marvel at the roaring Great Falls, one of the biggest waterfalls in the eastern United States, explore the national park around it, or learn how machines were once powered by rushing water.
The Great Falls is a thundering 77-foot waterfall in the middle of the city, and a national park now protects this natural wonder.
Paterson was one of America's first factory towns, where the power of falling water helped people make silk, trains, and even airplane engines.
