This episode is a rebroadcast that we first published in late September of 2019 around the 18th anniversary of the 9/11 attacks. We spoke with Alice Greenwald - National September 11th Memorial and Museum President and CEO. And she shared with us how a series of stone monoliths at the site of the memorial – known as the Glade – came to be and its purpose. And while it was temporarily closed to the public during the pandemic for safety reasons, the space has reopened to welcome visitors once again.
