Within The Wide Sargasso Sea, Antionette refers to what we know as Thornfield Hall as "The Great House." With the assumption that our unnamed narrator is Rochester, it is safe to also assume The Great House Antionette is trapped within is Thornfield hall from Jane Eyre. The two locations marked below (Hathersage, Derbyshire (above) and North Yorkshire (below)) are assumed to have served as inspiration for Brontë, and thus, serve as inspiration for Rhys, even if she was unaware at the time of writing her own rendition of Bertha (Antionette) and her story. The Great House is important in understanding the approach to the climax of Antionette's story. Antionette is trapped within the attic of the estate, left to slowly fall into the madness of her mind as she begins to hallucinate, explore, and eventually, burn down the house. The Great House represents the oppression and dehumanization the Caribbean was forced to endure at the hands of Great Britain as Antionette is forced into its attic, stripped of her name/autonomy, and ultimately forced into a life she has no understanding of. She doesn't even know the name of the estate. The location of The Great House is important when considering where Antionette's story begins and the colonial relationship between Great Britain and the Caribbean. The estate also represents the force of the patriarchy in relation to Antionette's freedom, as any she may have had before the attic is stripped away completely within The Great House.
