There is so much to love about Hogwarts, and one of my very favorite things at the school of magic is the enchanted ceiling. The ceiling of the Great Hall in Hogwarts has been enchanted so that it looks just like the outside sky is above them. Hermione Granger explained the magical ceiling to Harry Potter in Harry Potter and the Sorcerer's Stone, "It's bewitched to look like the sky outside. I read about it in Hogwarts: A History."
As much as we might want to have our own ceilings bewitched in the same way, we can't. What we can do is paint our ceilings to look like the night sky, which is what one family has done in the picture below.
One room of their house has stars painted on it, with colors that make it look like twilight. There is also subtle lighting to help light up the ceiling's night sky. The result is beautiful!
