Entry to the memorial plaza with its twin reflecting pools will still be free, but the decision to charge for the underground museum housing relics of the terror attacks has been greeted with dismay by some relatives of trade center victims.
Memorial foundation head Joseph Daniels said Saturday that the museum has little choice.
It is expected to cost nearly $60 million a year to operate the site.
Daniels said the museum will be free during certain hours every week.
The exact price of admission has not yet been determined.
