What is the Holocaust Museum's official web address?

The best-known Holocaust museum in the United States is the United States Holocaust Memorial Museum in Washington, D.C., and its official website is ushmm.org. Many organizations have dedicated parks, memorials and museums to historical information about the Holocaust, as well as the memory of its victims and survivors.

The Holocaust occurred in several countries in Europe, most widely in Germany, Poland, the Soviet Union, Hungary and Czechoslovakia, but the entire world was affected by its tragedy. In response, 27 countries have built monuments and museums to memorialize the event. There are more than 45 of these sites in the United States alone.
