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.

But of course, there are lots of carvings as well. Here is a monkey, playing the harp. That is what I thought, when I took the photo, but meanwhile i know, that the musician is a dog.
