Belle Reeve is a fictional plantation home featured in the play "A Streetcar Named Desire" by Tennessee Williams. It serves as the ancestral home of the character Blanche DuBois and symbolizes her lost heritage and the decline of the Southern aristocracy. The name translates to "Beautiful Dream" in French, reflecting the idealized past that Blanche clings to. The estate is described as having once been grand but has fallen into disrepair, mirroring Blanche's own deteriorating mental state. Its loss represents the broader themes of decay and the struggle between reality and illusion in the play.
