Founded in 1984, the Holocaust Memorial Center was the first institution in the United States to offer exhibits about the Nazi extermination of six million Jews in Europe during World War II. It's an eye-opening and breathtaking museum, offering a wide range of information and raising important questions about history. The the size of the center has been tripled by the addition of wings, including the Museum of European Jewish Heritage and the International Institute of the Righteous, celebrating Jewish culture in Europe and the heroes of the resistance. Admission is free.
