7. Visit the Skyscraper Museum’s SKYLINE Exhibit

The Skyscraper Museum’s new exhibit SKYLINE examines the history of New York City’s famous skyline broken down into five periods from 1876 to today. The final era focused on the skyline from 1961-2000, with an emphasis on the Twin Towers, once the tallest buildings in the world until they fell in the 2001 September 11th terrorist attacks.
