Which architectural style is characterized by regular, unadorned geometric forms?

The International Style is characterized by its emphasis on minimalism, functionality, and the use of regular, unadorned geometric forms. This architectural style emerged in the early 20th century and is known for its rejection of decorative elements in favor of simplicity and clarity in design. Buildings designed in this style often feature large glass windows, open spaces, and structural elements that are visible, showcasing a sense of modernity and efficiency.

The emphasis on geometric shapes and a lack of ornamentation effectively convey a sense of harmony and balance, which is a hallmark of the International Style. This approach aligns with the broader movements of modernism, focusing on industrial materials and the idea that form should follow function. In contrast, architectural styles such as Gothic, Baroque, and Renaissance are known for their intricate details, decorative elements, and historical references, which differ greatly from the clean lines and functionality celebrated in the International Style.
