The North Pool sits in the footprint of the former North Tower. The names of the 2,983 people who were killed in the 2001 and 1993 attacks are inscribed on the parapets edging the pools. The North Pool parapets include the names of those who were killed at the North Tower, on hijacked Flight 11, and in the 1993 bombing.

The South Pool sits in the footprint of the former South Tower and includes the names of first responders, as well as those who were killed at the South Tower, on hijacked Flight 175, at the Pentagon, on hijacked Flight 77, and on hijacked Flight 93.

In October 2001, a severely damaged Callery pear tree was discovered at Ground Zero. Members of the NYC Parks and Recreation Department removed it from the site and nursed it back to health, and it was returned to the World Trade Center site in 2010 and now stands on the Memorial as a symbol of perseverance.

The southwestern area of the Memorial plaza is dedicated in honor of all who are sick or have died from exposure to toxins in the aftermath of the 9/11 attacks, including first responders and recovery workers at all three sites, relief workers and volunteers, survivors, and lower Manhattan residents, students, and workers.

These historic remnants of the Twin Towers’ façade are 70-foot high columns known as “tridents” for their three-pronged tops. They were salvaged from the North Tower and are installed in the Museum Pavilion.

Built to hold back the Hudson River, this section of the original retaining wall remains exposed as a symbol of resilience in Foundation Hall.

One of the core columns of the South Tower, this was the last piece of structural steel to be removed from the World Trade Center site during the clean-up after 9/11. It is covered with markings, pictures, and tributes from different agencies and individuals and represents the community that formed during the recovery at Ground Zero.
