Which French cathedral is known for its three magnificent rose windows?

The French cathedral known for its three magnificent rose windows is Chartres Cathedral.

The three great roses occupy the west façade and the north and south transepts. They are celebrated not only for their scale but also for their dense medieval stained glass, whose deep blues, reds, and purples transform the interior light. The western rose depicts the Last Judgment, while the northern window is dedicated to the Virgin and the southern rose presents imagery associated with Christ’s heavenly glory.

Chartres’s windows survived remarkably well compared with those of many other medieval churches. The cathedral contains 167 windows in total, including rose windows, oculi, and tall lancets. Its structural system of pointed arches, rib vaults, and flying buttresses permitted higher walls and larger openings for glass.

The cathedral is sometimes confused with Notre-Dame de Paris, which also has famous rose windows. Chartres, however, is particularly identified with the trio of large roses and its exceptionally preserved stained-glass program.
