The Flight 93 National Memorial is a memorial built to commemorate the crash of United Airlines Flight 93, which was one of four aircraft hijacked in the September 11 attacks. The memorial is located in Stonycreek Township, Somerset County, Pennsylvania, about 2 miles north of Shanksville and 60 miles southeast of Pittsburgh.
The national memorial was created to honor the passengers and crew of Flight 93, who stopped the terrorists from reaching their target by fighting the hijackers. A temporary memorial to the 40 victims was established soon after the crash. The first phase of the permanent memorial was completed, opened, and dedicated on September 10, 2011. The design for the memorial is a modified version of the entry Crescent of Embrace by Paul and Milena Murdoch.
A concrete and glass visitor center opened on September 10, 2015, situated on a hill overlooking the crash site and the white marble Wall of Names. An observation platform at the visitor center and the white marble wall are both aligned beneath the path of Flight 93.
