The National September 11 Memorial & Museum occupies the World Trade Center site in Lower Manhattan, where the Twin Towers stood before the September 11, 2001 attacks. The memorial, "Reflecting Absence," designed by Michael Arad, consists of two recessed reflecting pools set within the towers' original footprints, each surrounded by more than 400 swamp white oak trees and fed by what are described as the largest man-made waterfalls in the United States. Construction began in March 2006, and the memorial opened to the public on September 12, 2011, the day after its dedication, drawing more than a million visitors within its first three months. The underground museum, designed by Davis Brody Bond with an entry pavilion by Snøhetta, opened in May 2014 and holds a large collection of photographs, artifacts, oral histories and video documenting the attacks and their aftermath, alongside preserved structural remnants such as the Survivors' Staircase and the Last Column.

The memorial and museum are located at 180 Greenwich Street in Lower Manhattan, on the former World Trade Center site.

The memorial's outdoor plaza is subject to New York City's four-season climate, while the museum itself is fully indoors and climate-controlled; specific seasonal temperature figures were not confirmed in the sources used for this entry.

Because the memorial plaza is outdoors, spring and fall generally offer the most comfortable conditions for lingering at the reflecting pools, while the indoor museum can be visited comfortably in any season. The memorial is open daily year-round from 8 a.m. to 8 p.m.

Construction on the memorial and museum began March 13, 2006. Michael Arad's "Reflecting Absence" design, chosen through a competition, places two recessed pools within the Twin Towers' footprints. The memorial was dedicated on September 11, 2011, for victims' families and opened to the general public the next day; within three months, more than a million people had visited. The museum was dedicated May 15, 2014, and opened to the public May 21, 2014. Together the site honors 2,977 victims of the September 11, 2001 attacks and six victims of the 1993 World Trade Center bombing.

Visitors can walk the memorial plaza and view the two reflecting pools inscribed with victims' names, using the free audio guide available through the Bloomberg Connects app. Inside the museum, exhibits include the Survivors' Staircase, the Last Column, recovered Twin Towers steel, the World Trade Center cross, and tower tridents, drawn from a collection of more than 40,000 images, 14,000 artifacts, 3,500-plus oral history recordings and over 500 hours of video; audio guides are available in nine languages including ASL.
