The castle appears to have thick tall walls that also serve as the base, 3 predominant sections of towers each connected by arches. Most of the spires are pink in color and there are 17 seen. The "castle in the air" if you will, seems to face west through the entrance is undefined (as it is for a lot of other Disney castles.)
The Prince, searching for Snow White following her mysterious disappearance from her castle, learns of a maiden that lies in a glass coffin and visits the vigil's location in the forest. Unknownst to him, Snow White is actually poisoned by her stepmother, the Evil Queen. Upon arriving at the forest, he recognizes that the maiden is Snow White and sorrowfully sings a reprise of "One Song" as he places one last kiss on his seemingly deceased love. To the surprise of the Prince, and surrounding seven dwarfs, Snow White awakens from her curse through "true love's kiss" and warmly embraces her prince. Reunited, the Prince and Snow White ride off to the former's castle to finally begin their lives together.
Some fans believe that the ending of Snow White and the Seven Dwarfs shows the Prince and Snow in Heaven when the castle is shown, because of it looking like the castle is in the clouds.
