Yad Vashem, the World Holocaust Remembrance Center, is entrusted with the task of commemorating, documenting, researching and educating about the Holocaust: remembering the six million Jews murdered by the German Nazis and their collaborators, the destroyed Jewish communities, and the ghetto and resistance fighters; and honoring the Righteous Among the Nations who risked their lives to rescue Jews during the Holocaust. Yad Vashem encompasses 45 acres on the Mount of Remembrance in Jerusalem and is comprised of various museums, research and education centers, monuments and memorials. Among these are the Museum Complex, the Hall of Remembrance, the Valley of the Communities and the Children’s Memorial.
