The rose window of the Strasbourg cathedral is, with its 13.60m diameter, one of the largest of the medieval world and a perfect illustration of the Rayonnant Gothic. It sits in the centre of the Westwerk and has been constructed around 1330 by Meister Johannes, the nephew of Meister Erwin.

In the attic of the cathedral, there is a shutter which nearly face the rose, and it’s always a magic moment when you open it and are directly confronted to this masterpiece.
