Three hours was needed to really see and take in everything that the museum has to offer. A good hour is needed outside to appreciate what happened there, to see the reflecting pools in the footprints of the original towers, and to read some of the names of those whose lives were lost.

Yes I found the tour excellant to get a more personnel view of the memorials then you go right into the museum avoiding the long lines outside well worth to do it this way

el museo no es gratuito como todo lo de New York pero ver la fuente con los nombres de los muertos si.

The Catholic memorial is in the Chapel of St. Joseph on the south side of the North Cove boat basin in Battery Park City, across the street from the World Trade Center. The official street address is 385 South End Avenue. There are statues of saints related to St. Florian for firefighters, St. Michael for police, St. Joseph for the workers in the building who died in the attacks and workers who worked for months after in on the site, and Mary Magdalene for all those who mourn. The National 9/11 Memorial is on the original site of the World Trade Center, just south of the new WTC. It is a plaza with the pools within the footprints of the towers, where the names of the people who were killed are inscribed.
