Coimbra library ceiling .
The reason that the ceiling looks pristine is that the library is unlit, no light is permitted so no flash on the camera also no noise so no shutter, but my camera has an e-shutter and I cradled it upwards and pressed the shutter. The library is kept in near darkness to preserve the books some of which are centuries old i.e. over 500 years. Also you have limited time inside to limit the humidity from your breath, so if you visit be aware of the limitations that you will face.
