The typical cathedral contains a narthex at the entrance, three aisles with the central being the nave, a transept that gives the church its cross shape, an open choir where the nave and transept meet, and an apse at the far end of the nave, containing the altar.
Not only were the arched windows tall in proportion, but gothic cathedrals often included lofty pointed steeples. Gothic architects did not strive for symmetry, as is famously seen in the west façade of Chartes Cathedral, where the two steeples do not match.
Its innovations, including flying buttresses, three rose windows, many smaller stained glass windows, and the sculptural carvings around the portals, came to exemplify the Gothic style.
