How is setting described in a play?

The setting is where and when the story takes place. What is the most interesting setting you have found in a work of fiction? A battlefield? A haunted house? Another planet? Some of the best fiction ever written takes place in the most hum-drum environments: a suburban house, a farm, a small village. The eighteenth-century writer, Xavier de Maistre, wrote a travel book set entirely in his bedroom, where he was confined for weeks after being wounded in a duel.
