Gothic architecture developed between 1150 and 1400 AD in Europe. It evolved from Romanesque architecture with key innovations like pointed arches, rib vaulting, and flying buttresses that allowed for taller buildings with larger windows. Gothic cathedrals became important symbols of towns and featured stained glass, sculpture, and elaborate tracery. The style progressed through experimental, classical, and flamboyant stages before declining at the end of the 15th century.
