Poitiers - Cathedral

On the ruins of a older basilica begann, just next to the Baptistère Saint-Jean the construction of large Cathédrale Saint-Pierre in 1162. The building, the new the seat of the Archbishop of Poitiers, was greatly funded by Henry II of England (aka "Henri II Plantagenêt") and Eleanor of Aquitaine.

The construction started as usual in the east and was completed with the western facade end of the 13th century.

The cathedral is best known for the wonderful stained glass windows. The three windows around the choir date back to the 12th century and may be the oldest in France.

The windows of the eastern part of the nave may be some decades younger. so they will be created in the early 13th century.

I will upload some details of them.

I am not sure about this.

In case on the left is Mary in childbed, then below her is Jesus having his "First Bath". Supported by a midwife.
In case to the right is a camel/dromedary, then the three men may be the Magi. But where is the Star of Bethlehem?
