Adolf Hitler goes on a three-hour tour of the architecture of Paris with architect Albert Speer and sculptor Arno Breker in his only visit to the city.

The city of Paris has notable examples of architecture from the Middle Ages to the 21st century. It was the birthplace of the Gothic style, and has important monuments of the French Renaissance, Classical revival, the Flamboyant style of the reign of Napoleon III, the Belle Époque, and the Art Nouveau style. The great Exposition Universelle (1889) and 1900 added Paris landmarks, including the Eiffel Tower and Grand Palais. In the 20th century, the Art Deco style of architecture first appeared in Paris, and Paris architects also influenced the postmodern architecture of the second half of the century.

Berthold Konrad Hermann Albert Speer was a German architect who served as Minister of Armaments and War Production in Nazi Germany during most of World War II. A close friend and ally of Adolf Hitler, he was convicted at the Nuremberg trials and sentenced to 20 years in prison.

Arno Breker was a German sculptor who is best known for his public works in Nazi Germany, where he was endorsed by the authorities as the antithesis of degenerate art. He was made official state sculptor, and exempted from military service. One of his better known statues is Die Partei, representing the spirit of the Nazi Party, which flanked one side of the carriage entrance to Albert Speer's new Reich Chancellery.
