Bethlehem's National Museum of Industrial History gives an in-depth history of the industries that shaped Bethlehem and the surrounding areas during the industrial revolution. The Hoover Mason Trestle is another great attraction that showcases some of the history and culture of Bethlehem. It is an elevated walkway that runs along the former Bethlehem Steel Plant, now known as Steel Stacks. Bethlehem is also home to the Morvian Historical Society Museum, the oldest museum in the country, as well as the Morovian Bookstore, the oldest bookstore in the country.

2. Bethlehem Steel Stacks/Hoover Mason Trestle

For most of its history, Bethlehem Steel had its headquarters in Bethlehem, Pennsylvania, in the Lehigh Valley region of the United States. What used to be Bethlehem Steel Corporation is now Bethlehem Steel Stacks. Bethlehem Steel was a steel company based in Pennsylvania. Until 2003, it was one of the biggest steel and shipbuilding companies in the world. A symbol of American manufacturing leadership at its peak, the company's decline and eventual liquidation are also examples of its diminished status. Bethlehem steel was used in many of America's most famous structures. Some of the biggest ones were 28 Liberty Street, the Chrysler Building, the Empire State Building, Madison Square Garden, and Rockefeller Center.

3. Christmas City in Bethlehem, PA

Christmas City is a nickname for Bethlehem. David Nitschmann and Count Nicolaus Zinzendorf founded a Moravian mission there on Christmas Eve 1741. With the first residents came the so-called Moravian star, an intricate illuminated decoration associated with Christmas or Epiphany. The original 25-point design, known as an augmented rhombicuboctahedron became popular enough to warrant commercial production, and now similar stars have as many as 110 points. Over 20 miles away, the illuminated northern and southern faces of the Christmas Star atop South Mountain can be seen.
