In "A Rose for Emily", how is Miss Emily's house symbolic?

Miss Emily's house, like Miss Emily, is a symbol both Emily and the decaying South. Her house, is described as once being a "grand house" ‘‘set on what had once been our most select street.’’ However, by the end of the story her house and the neighborhood it is in have deteriorated. The narrator notes that prior to her death, the house “had once been white,” and now it is the only house left on the block. It has become “an eyesore among eyesores". This mirrors Emily's deterioration and with it the deterioration of the "Old South" and its way of life. Emily's father had been once of the most respected men in the town. However, he left Emily virtually penniless with only her family reputation behind her. As the story unfolds, we see Emily's deterioration into delusion and, probably, madness. By the end of the story, Emily, like her house, has become a "fallen monument" to the people of the town and to the old Southern lifestyle.
