This museum is mainly a collection of photographs taken by a professional photographer who was granted exclusive access to Ground Zero. There are also small artifacts in the museum. Wonderful descriptions of the items and photographs. There is an audio tour that takes about 1 1/2 hours. It was an emotionally moving experience. Very small, basically one room, but worth the cost. We took our two teenagers and they were engaged looking at the items and listening to the descriptions. I highly recommend going to this museum.
