In the Nasrid Palace (Grenada, Andalusia) there are several insanely detailed, beautiful dome ceilings. This picture is of the 8 point star 'stalactite' roof looking like the cosmos. It is the work of Sultan Muhammad V carried out around 1362.

The dome rooms in this palace are so big that you can't even find a good quality, symmetrical picture capturing the entirety of the beauty the rooms offer.
