Final answer:
Nazi architecture was characterized by a Classical revival, monumental scale, and the use of indigenous materials, with a focus on symmetry and tradition over individualism and organic forms.
Step-by-step explanation:
The architecture under the Nazi regime was notable for its Classical revival and monumental scale. Rejecting the experimental and individualistic approach of Expressionist architecture, the Nazis promoted a form of architecture that echoed the grandeur and authority of classical antiquity, favoring symmetry and simplicity closely associated with Neoclassicism. This classical influence was considered appropriate for representing the strength and purity of the regime, and thus they built on a grand scale to make an impression of power and permanence. Unlike the curvature and naturalism favored in both Expressionist and Art Nouveau styles, Nazi architecture was more rigid and austere, emphasizing grandiose and intimidating structures.
Architectural elements aimed at invoking a sense of national pride and heritage, often incorporating indigenous materials. The regime, however, showed less interest in organic forms, preferring instead to exalt conventional beauty through grand, symmetrical, and heroic designs. This emphasis on tradition and rejection of Modernism culminated in the infamous Entartete Kunst (Degenerate Art) exhibition of 1938, which condemned modern and abstract art that did not align with the regime's aesthetics.
