National September 11 Memorial & Museum
2h 30m · Museum · Landmark
Two things, priced differently. The outdoor memorial — the twin voids on the tower footprints, with every name cut into the bronze parapet — is free and open daily from 08:00 to 20:00. The museum below is ticketed, open 09:00 to 19:00 Wednesday through Monday and closed most Tuesdays, so check the day before you plan around it. Admission is free on Mondays from 17:30, but tickets are released online that same morning and 90 minutes is not enough time inside; a booked morning slot is the honest version. The museum's own guidance is ninety minutes; allow more if you read rather than walk. The Oculus, the white ribbed hall next door, is the station and shopping centre, and costs nothing to walk through.
