The 9/11 Memorial & Museum is a history museum built at the site where the World Trade Center twin towers collapsed in New York, alongside a memorial park. Its exhibits present the period before the attacks, the attacks themselves, and the recovery work afterward in sequence, using actual building debris, objects, video, and photographs. Book the morning of the day before your visit, and scan the QR code at the line to enter; the visit takes about two to three hours. The exhibition content is heavy and can be emotionally difficult.
