Certainly the rotting bridal cake of Miss Havisham and her yellowed wedding dress are symbolic of the wasted life of a once beautiful woman who was abandoned by her fiancee on her wedding day.

Time has stood still; she has all her clocks stopped at fifteen minutes until the hour of the wedding that did not occur many, many years ago. It is, indeed, ironic that Miss Havisham's wedding dress, rotting cake, stopped clocks, and darkened rooms become symbolic of death and devastation.
The name of her mansion is also symbolic: Satis House. The irony of this name cannot be missed by readers as they perceive the unhappy lives within: an old woman who seeks revenge upon the male population as she raises a beautiful young woman to be heartless and cruel to men.

On the other hand, the Forge symbolizes warmth and love for Pip, who initially rejects it as "common" in his desire for wealth and status as a gentleman.
