One of the bathrooms in the Château Lumière with a little sunlight peaking in. But assumably in the past all doors were closed during “business hours” and due to no windows, only artificial light was available.
Today the kitchen stays cold and the supplies are out! As all the staff is currently absent, visitors are kindly advised to bring their own victuals to clean up after themselves.
In the center of the Château Lumière, a big light-well lets sunlight pass down through the building to the ground floor.
