This is the amazing and ancient 10th century chapel of the medieval fortress of Berze le Chatel. It was constructed within the tower and fortifications of the fortress with no outside access. The worshippers had to enter down the narrowest and steepest of stone stairway from within the castle. The light you see streaming in from the right by the alter is a door that was constructed in the late 18c. Directly behind me within the chapel there is also a Pagan worshipping cave, but far too dark to capture. This place has a a very special atmosphere and quite unchanged from when it was last used, mainly because the castle lain unused and empty for two centuries. I didn’t want to leave but on a guided tour one cannot linger.
