This room was chill, because it seldom had a fire; it was silent, because remote from the nursery and kitchen; solemn, because it was known to be so seldom entered. The house-maid alone came here on Saturdays, to wipe from the mirrors and the furniture a week’s quiet dust: and Mrs. Reed herself, at far intervals, visited it to review the contents of a certain secret drawer in the wardrobe, where were stored divers parchments, her jewel-casket, and a miniature of her deceased husband; and in those last words lies the secret of the red-room – the spell which kept it so lonely in spite of its grandeur.
Mr. Reed had been dead nine years: it was in this chamber he breathed his last; here he lay in state; hence his coffin was borne by the undertaker’s men; and, since that day, a sense of dreary consecration had guarded it from frequent intrusion.

Jane Eyre, Chapter 2. When Jane is locked in the red room, the alienation and ostracization she feels while living with her aunt is reflected in the description of the room. The room is depicted as chilly, isolated and abandoned – echoing her own harsh life in the home of her cruel aunt Mrs. Reed, who visits the room on rare occasions to check the contents of a secret drawer.
