Fagus Factory, located in Alfeld, Germany, is a pioneering example of modern industrial architecture. Designed by architect Walter Gropius and built between 1911 and 1913, it is recognized for its innovative use of glass and steel, which allowed for natural light to illuminate the workspace. The factory was primarily used for the production of shoe lasts, showcasing the integration of functionality and aesthetic design. In 2011, Fagus Factory was designated a UNESCO World Heritage Site, highlighting its significance in the development of modern architecture. The building's design influenced many future industrial structures and is considered a precursor to the Bauhaus movement, which emphasized simplicity and the unity of form and function.
