Which architectural style is characterized by features such as flying buttresses and ribbed vaulting?

The architectural style characterized by features such as flying buttresses and ribbed vaulting is the Gothic style. This style emerged in the 12th century and became prominent during the High and Late Middle Ages across Europe, particularly in cathedrals and churches. Flying buttresses were innovative structural elements that allowed for the construction of taller and more expansive walls with large stained glass windows, enhancing both aesthetic appeal and interior illumination. Ribbed vaulting was another significant advancement that provided strength and support to ceilings, allowing for more complex and varied forms.

The use of these elements illustrates the Gothic movement's emphasis on verticality and light, creating an ethereal and grand atmosphere in ecclesiastical architecture. In contrast, Art Deco, Prairie, and the Chicago School of architecture showcase different characteristics and themes that do not focus on the same structural innovations associated with Gothic design. For instance, Art Deco is known for its decorative style and bold geometric shapes, the Prairie style emphasizes horizontal lines and integration with the landscape, while the Chicago School is recognized for its pioneering use of steel-frame construction and large plate glass windows.
