The 9/11 Memorial & Museum
The 9/11 Memorial tells New York’s toughest story through water, light, and steel.
Two acre-sized pools drop into the ground where the Twin Towers once rose, while a museum below holds items from first responders and survivors.
Here’s an inside look at this powerful tribute to September 11.

America Rebuilds From Terror’s Ashes
“We will rebuild.”
Mayor Rudolph Giuliani’s declaration echoed through a dust-covered city just hours after the September 11 attacks.
His words began the long journey toward creating a memorial at Ground Zero.
Not a single inch of the Twin Towers’ footprints would be disturbed. The Port Authority made this clear in 2002, declaring these exact locations sacred ground.
The National September 11 Memorial & Museum finally incorporated and held its first official board meeting on January 4, 2005.

5,000+ Designs Competed For the Honor
The 9/11 memorial design competition launched April 28, 2003. Anyone could join, regardless of their experience or background.
Designers submitted an astounding 5,201 proposals from 63 countries.
The selection jury included Vietnam Veterans Memorial designer Maya Lin alongside twelve others.
Michael Arad, a 34-year-old architect who had served in the Israel Defense Forces, won with his “Reflecting Absence” design on January 6, 2004.

Twin Voids Transform Into Reflecting Pools
Workers began the meticulous granite installation on April 22, 2010. Stone by stone, they lined the pools.
The North Pool was completed first in June, with the South Pool following weeks later. Water would cascade 30 feet down, then drop another 20 feet through a central void. Nothing like it had been built before in North America.
Ten pumps now push 52,000 gallons per minute through the system. The resulting sound masks city noise, creating a contemplative space amid Manhattan’s bustle.

Bronze Parapets Honor Every Life Lost
Alphabetical listings felt coldly bureaucratic for the names of nearly 3,000 victims. Memorial designers rejected this approach immediately. Instead, they went with something more meaningful.
These parapets would place friends, colleagues, and flight crews together as they had lived and died, honoring real human connections.
Over 1,200 requests flooded in from victims’ families seeking specific name placements. Software designer Jer Thorp created a complex algorithm to solve this emotional puzzle.
The North Pool carries the names of North Tower victims, Flight 11, and those killed in the 1993 bombing. Waterjet cutting machines precisely carved each name into bronze parapets surrounding the pools.

Hundreds of Trees Create Living Memorial
Landscape architect Peter Walker chose swamp white oaks for the memorial plaza.
This hardy species naturally grows near all three 9/11 crash sites – a living connection to New York, Pennsylvania, and Virginia. Specially engineered soil arrived at Ground Zero in July 2010.
Scientists had perfected this mixture through years of testing to sustain trees growing above the concrete and steel infrastructure. August saw the first saplings take root.
For years before installation, they had grown together at a New Jersey nursery, acclimating to identical conditions. This ensured uniform health at their final home.
Between straight rows and formal pools, Walker created peaceful groves where visitors find shade and contemplation away from the rawness of the voids.

One Scorched Tree Becomes A Symbol
Recovery workers spotted something unexpected amid October 2001’s devastation – a Callery pear tree. Horribly damaged but somehow alive, it emerged from the wreckage like a miracle.
“It was just a stump with one living branch,” recalled Parks Department Director Ron Vega. His team worked carefully, extracting the tree from Ground Zero’s twisted steel without causing further damage.
Horticulturists at Van Cortlandt Park in the Bronx refused to give up on the battered tree. Months passed. Against overwhelming odds, new branches sprouted from the charred trunk. Life persisted.
By 2010, the tree’s resilience had captivated public imagination. Now thriving and standing three times taller than when rescued, it had become a living metaphor for New York itself.
A police escort accompanied the “Survivor Tree” back to Ground Zero that December. Mayor Bloomberg helped replant it near the South Pool, where it stands today – a single tree telling the story of a wounded city’s revival.

Museum Construction Reaches Bedrock
Excavators dug 70 feet below street level, creating the museum at Foundation Level. This depth wasn’t arbitrary – it was precisely where the Twin Towers once stood.
The Survivors’ Staircase arrived at the site in July 2008. Engineers used specialized equipment to lower this critical artifact to bedrock, preserving the concrete steps that had served as an escape route for hundreds fleeing the attacks.
“Build around it, not over it.” This instruction guided museum planners’ approach to the 36-foot Last Column. The massive steel beam carried too much symbolic importance to move after construction.

The Museum’s Stunning Glass Facade
In 2013, the glass curtain wall surrounding the museum’s entryway rose into place. Made of 40-foot high panes, it allows visitors to view the surrounding memorial as they approach.
The transparent design echoes themes of openness and remembrance, while providing an unobstructed view of the trees, pools, and the South Tower footprint.
The glass façade was crafted to reflect light from the surrounding space, symbolizing both the transparency of history and the openness to healing.

The Collection of 9/11 Artifacts
As the museum’s construction progressed, the painstaking work of curating thousands of artifacts began.
From a damaged fire truck to a pile of shoes recovered from the rubble, these items told the personal stories of those who experienced that fateful day.
One of the most poignant pieces was a battered section of the American Airlines Flight 11 fuselage, which collided with the North Tower.

The National Tribute
The 9/11 Memorial & Museum was officially opened to the public on September 11, 2011, on the tenth anniversary of the attacks.
The memorial has since become a national and international tribute, drawing millions of visitors from all over the world.

Remembering the First Responders
The memorial and museum make a special effort to honor first responders who risked and gave their lives during the attacks.
In addition to the main exhibition, the space includes tributes to firefighters, police officers, emergency medical personnel, and volunteers who assisted in the recovery efforts.
Artifacts related to first responders, such as uniforms, radios, and tools, serve as symbols of bravery and sacrifice.
