Poe's Short Stories Palace Map for "The Masque of the Red Death"

There are seven rooms in Prince Prospero's imperial suite, which are segregated by sharp turns. Gothic stained glass windows on each side of the room look out into the surrounding corridor. Each room features a different color, which matches the color of the window: the first room is blue, the second purple, the third green, the fourth orange, the fifth white, and the sixth violet. Opposite each window, in the corridor outside the room, was a brazier of fire, whose light shines through the stained glass windows. In the seventh room, however, while the dominant color is black, the windows are a scarlet red. Here, the light from the fire creates such a ghastly effect that most of the guests avoid the room altogether. Moreover, a giant ebony clock’s pendulum swings ominously at the revelers.
