Daniel Libeskind on the 20th Anniversary of 9/11

Polish-American architect Daniel Libeskind, who designed the original Ground Zero master plan at the World Trade Center site, talks with us about his personal experience of the 9/11 attacks; how architecture can serve as an instrument for healing; and why the Tree of Life Synagogue he’s redesigning in Pittsburgh, to memorialize victims of the 2018 mass shooting there, represents a global vision for the future.
