9/11 Memorial Glade
9/11 Memorial Glade
Construction on the 9/11 Memorial Glade began in fall 2018 to create a pathway to honor the ongoing sacrifice of rescue, recovery and relief workers, and the survivors and members of the broader lower Manhattan community, who are sick or have died from exposure to toxins in the aftermath of 9/11. The Glade will also recognize the courage, selflessness and perseverance of the men and women of the rescue and recovery effort.
The planned dedication for the 9/11 Memorial Glade is May 30, 2019, the 17th anniversary of the official end of the recovery mission at Ground Zero. The Glade design was developed by the Memorial’s original architects, Michael Arad and Peter Walker, with the thoughtful support of 9/11-health advocates and providers, 9/11 family members, first responders and lower Manhattan residents.
The 9/11 Memorial Glade’s six stone monoliths were installed on Saturday, April 6. This process required a 600-ton crane and an assist crane. Each monolith, weighing between 13 and 17.8 tons, was lifted over the 30 to 35-foot-tall Swamp White Oak trees on the Memorial plaza and rigged inside the Glade construction site.
The monoliths traveled six hours south on flatbed trucks through the Green Mountains and the rolling hills of New England. Along the way, they were escorted by a team of eight personnel from the Vermont Division of Fire Safety. As the team assisted the trucks on their way to New York City, local first responders in communities along the way saluted the monoliths on the highway overpasses to recognize the importance and national significance of this project.
When they arrived in lower Manhattan, they met a scene of workers waiting to guide them safely into their permanent home. As the focal point of the 9/11 Memorial Glade, the monoliths’ rough edges and large size were created to honor the challenges faced by those whom the Glade memorializes.
The site has been prepared to support the weight of the monoliths through high-density Styrofoam, concrete and steel rebar. This reinforcement is essential because the monoliths sit on the Glade directly above the 9/11 Memorial Museum which extends 70 feet underground.
Within the construction site, workers will begin to lay the pathway stone (Verde Fontaine) around the monoliths. This stone, together with the modified irrigation and soil aeration systems, will ensure that the trees, grass, ivy beds and other landscape elements can thrive.
Also in the coming weeks, Monett Metals, a specialty steel-casting foundry in Missouri, will create the final design element of the monoliths. At the foundry, recovered World Trade Center steel will be melted down and formed to fit the fissures that were carved into the monoliths.
Two craftsmen in Barre, Vt., have transformed large blocks of quarried granite into the focal point of the 9/11 Memorial Glade. They used sledgehammers, chisels and blowtorches to shape the stone’s rough edges into the first of six massive monoliths, which play a central role in the most significant development of the 9/11 Memorial since its construction. Both stonemasons carried a profound appreciation for the challenges faced by those whom the Glade memorializes as they continue to work on this project.
- The 9/11 Memorial & Museum is leading in the planning, design and development of the Glade with the Memorial’s original architects, Michael Arad and Peter Walker. This ongoing collaboration ensures the site's aesthetic continuity and timeless sacredness.
- The $5 million cost depends on financial support from individual and corporate philanthropy as well as state appropriation. Former “The Daily Show” host Jon Stewart, who has advocated for 9/11-health benefits, is helping to lead a major fundraising effort. To date, New York State (through its affiliates), Bloomberg Philanthropies and the Building Trades Unions committed to funding a portion of the project.
- The design includes a pathway flanked by six large stone monoliths pointed skyward that are worn, but not beaten, symbolizing strength and determination through adversity.
- The Glade’s physical location marks the historical placement of the main ramp which provided access to bedrock during the recovery period. In the history of the World Trade Center, the ramp played an essential role allowing victims’ families to access the site following the attacks as well as workers who removed debris and established a pathway for rebuilding.
- Each monolith weighs between 13 and 17.8 tons. Their design will incorporate steel from the original World Trade Center inspired by a Japanese art technique called kintsugi.
- An inscription developed in consultation with stakeholders to complement the physical design will be unveiled at the dedication on Thursday, May 30, 2019.
