The New York City Police Museum has opened a permanent exhibit dedicated to the 23 city officers killed in the terrorist attack on Sept. 11, 2001.

Although the Port Authority and Fire Departments lost more people to the attack, the City Police was affected as well, and received much less public attention. The display helps demonstrate to visitors the role New York City police officers had that day and in the aftermath.

Called “9.11 Remembered,” the exhibit includes a presentation shown on two flat screens designed to resemble the two towers. Items belonging to City police officers that died in the attack are on display, as are letters from children and others offering their condolences.

Until recently, the museum was housed in the police academy building. But it has been moved to an ornate building that was home to the 1st Precinct. Now, the museum is much more visible and new police recruits tour the museum as a part of the academy.
