What is the setting of The Pit and the Pendulum by Edgar Allan Poe?

The setting for Poe's Pit and the Pendulum is during the Spanish Inquisition where the narrator has been sentenced to death. The Inquisitors were not known for their humane death sentences, so the reader knows it isn't going to be pretty. However, since the tale is being told from the past tense, it is certain that the narrator does survive it.
