This stunning memorial was created to honor the people killed on September 11, 2001. Almost 3,000 people lost their lives on September 11, 2001 when terrorists flew planes into the Twin Towers, causing them to collapse. The memorial consists of two pools set in the original site as well as a beautiful plaza. The names of the victims are engraved on paneling along the pools. Visitors can also explore the 9/11 Memorial Museum that features artifacts and stories about the events.
