Gothic architecture originated in northern France in the 12th century and spread across Europe over the following centuries. Key features included pointed arches, ribbed vaulting, flying buttresses, and large stained glass windows. This allowed for taller, lighter structures with more openings. French Gothic cathedrals like Notre Dame and Chartres featured elaborate tracery and stained glass, while English cathedrals like Salisbury emphasized surface ornamentation. German Gothic was highly inventive with complex vaulting and fluid spaces.
