When "Northanger Abbey" is introduced, Jane Austen paints a vivid picture of the starting point of Catherine's journey, which happens to be Northanger Abbey. Although Catherine was born in Fullerton, throughout the novel the reader witnesses the transformation and growth of young Catherine. This is the reason why the novel can be considered a bildungsroman. Catherine grows and matures as a person, moves to a new place and discovers a new way of perceiving her surroundings. At first, Catherine's wide-eyed innocence is untouched or affected by reality, she is enthusiastic about everything and trusts everyone. She has had no experience in life to shatter her childish illusions, and these illusions are free in Northanger Abbey. As Catherine grows up and faces many obstacles in her life, she finally decides to go to Woodston and Woodston is a place or reality for her. Woodston is the stage in her life where she begins to see life through her eyes and not through her novels. These two contrasting places are just one of the many doubles or pairs that Jane Austen uses in her novel to highlight herself. The theme of “two sides of a coin” is represented through its characters and even in the setting. When Catherine transitions to her "second side", she finds herself in a whole new place where she can be this new person with Henry. Northanger Abbey functions, in Catherine's life, as a place that is a slice of upper-class life and parental authority, but this same place functions as Catherine's imagined life. “Northanger Abbey!” These words were exciting and took Catherine's feelings to the highest point of ecstasy. His grateful and satisfied heart could hardly restrain its expressions in the language of tolerable calm. Without these two places, Catherine's transformation would not be as clear or as widespread. Catherine's journey takes her to a whole new place with a whole new life because in the end, she is a whole new Catherine. His personal characteristics are modified and his action has changed. is presented in the novel, she is a naive young girl and she becomes this woman who makes her own choices with her husband Henry in Woodston. Although Catherine continues to read her novels, she has discovered what life is like without the novel. She finally separated fiction from reality and that is the difference between Northanger Abbey and Woodston. They both look like normal places, but Catherine's worldview didn't completely change until she lived in the dark Northanger Abbey..
