The main feature of the Nazi Party Rally Grounds is an extensive museum (the Documentation Center / Dokumentationszentrum Reichsparteitagsgelände) which documents the history of Nazi Germany with a particular focus on Nurenberg's role in that history. The museum is located in one corner of the never finished shell of the Congress Hall, a massive building Hitler inteded to use for party meetings. There are also several other sites on the Rally Grounds which can be accessed through a walking tour including the Zepplin Field (the site of massive rallies).
