Gothic architecture originated in 12th century France and spread across Europe. Key characteristics include pointed arches, ribbed vaulting, flying buttresses, stained glass windows, and ornate sculptures. Gothic cathedrals had skeletal stone structures and emphasized light and visual symbolism. Regional variations developed, such as French cathedrals emphasizing height, English cathedrals appearing horizontal, and Italian cathedrals featuring colored marble and frescoes. Building materials also varied by region.
