Where can the oldest stained glass windows be found ?

Is it The Cathedral of Chartres in France??? After a fire, there were three remaining stained glass windows from the 11th century. There were others as well, but only these three are that old...

I came up with another that claims to be the oldest surviving stained-glass windows, the five windows (also 11th-century) are from Augsburg Cathedral in Augsburg, Germany. The windows are no longer in their original setting. They have been moved into a museum and replaced with copies.

Cathedral of Chartres Stained Glass (1145-1220)
--------
Testament figures in the clerestory of Augsburg Cathedral, dated either 1050-1060 or 1100-1150. The center for stained glass, however, became the Île de France region around Paris. The windows for the royal Abbey Church of Saint-Denis, commissioned by the famed Abbot Suger and made between 1144 and 1151 (now heavily restored), were soon followed by others at Chartres, Bourges, and Le Mans. Four resplendent windows, made between 1160 and 1170, in Chartres Cathedral miraculously survived the fire of 1194. Three of them, all lancet windows, remain in the west facade; the fourth window, the noble Notre Dame de la belle verrière, was placed in the 13th-century structure's ambulatory.

It appears that the Augsburg Cathedral windows are most likely the older. But then there is this: Face of Christ, Lorsch Abbey, Late Tenth Century - This is said to be the earliest surviving figurative glass in the west.
