A ceiling painted with stars frequently occurs as a design motif in a cathedral or Christian church, and replicates the Earth's sky at night. Ceilings painted with stars are often found in these buildings because of the symbolic associations of stars in Christianity, Judaism, and Islamic faith. In religious buildings, this decorative feature is often depicted with white or gold stars on a blue background. As well as being a decorative technique, star-painted ceilings are also associated with astrology. It has been used as a way to accurately depict the night sky, in planetariums, for example. Ceilings painted with stars are also a decoration feature sometimes found in houses, particularly in children's rooms.
