Sept. 11, 2011, marked the 10-year anniversary of the devastating attacks on the United States. The following are images taken from Jersey City's Liberty State Park across from Manhattan last year as well as this year.

I traveled from Toms River to Jersey City this and last year on and around Sept. 11 to capture some of the memorial activities. The lights have been going on for some time during Sept. 11, and this year was their last, but there's a new element to the memorial in Jersey City:

This year's photos include images of the new memorial unveiled this year, called "Empty Sky: New Jersey." The memorial is two concrete walls that resemble the twin towers. The inside of the walls are lined with stainless steel panels that have the 739 names of the victims from New Jersey. At the front of the memorial, two I-beams from the World Trade Center are displayed. 

This is the last year New York will be displaying the memorial lights.
