Classic Gothic (French: Gothique classique) is a French term for the second phase of Gothic architecture in France, as defined by French scholars. The common English term for the period is High Gothic. This is disputed by German scholars. The German definition of High Gothic requires bar tracery, which did not arrive in French cathedrals until the construction of Reims Cathedral, but the English definition does not.
The French definition of "Gothique Classique" calls for a long nave covered with quadripartite rib vaults and flanked by collateral aisles, a large transept, a choir, and a semi-circular disambulatory leading to a ring of small chapels. This model appeared at Chartres Cathedral and was copied at Reims Cathedral and other later structures.
