Hermann Giesler was a German architect during the Nazi era who designed several major Nazi buildings and complexes, including the Ordensburg in Sonthofen and Albert Speer's projects. The Ordensburg was a massive complex for ideological and political training of Nazi party members, with facilities for thousands of people. Albert Speer modernized Nazi architecture and oversaw grand projects like the Nuremberg rally grounds and a new Reich Chancellery built in record time, demonstrating Nazi Germany's power through monumental structures.
