Stanza 1
Once upon a midnight dreary, while I pondered weak and weary,

Over many a quaint and curious volume of forgotten
lore-

While I nodded, nearly
napping, suddenly there came a tapping,

As of someone gently rapping, rapping at my chamber
door.

"Tis some visitor," I muttered, "tapping at my chamber
door-
                                            
                                                Only this and nothing
more."

The first stanza of The Raven is about the speaker being in his chamber. He hears a tap at his door, and thinks it is some visitor calling at his door at midnight.
In this stanza, part of the setting is stated - we know the speaker is at his chamber, and we know that it is midnight.
