The 9/11 Museum is expected to open this spring underneath the World Trade Center’s memorial plaza. Many of the large artifacts including metal remnants from the original Twin Towers have already been installed, and officials with the National September 11 Memorial & Museum are excited by the opening. “Seeing the space become the museum we envisioned, and that we have worked so hard to create, is tremendously gratifying,” Alice Greenwald, 9/11 Memorial Museum director, said in a statement last month. “We believe that this historic museum that will tell the story of 9/11 and its aftermath through personal stories and powerful artifacts …will resonate deeply with visitors from around the world.”
