Portsmouth

In Mansfield Park, Fanny Price is sent from her home in Portsmouth to live with her aunts and uncles in Mansfield Park in Northamptonshire. Fanny's nine siblings still reside in Portsmouth, and her contact with most of them (excluding her older brother, William) is limited. When Fanny denies Henry Crawford's offer of marriage, she returns to her home in Portsmouth, with Sir Thomas Bertram hoping it will make her reconsider Mr. Crawford's offer. When she returns home, a home she had not seen since the age of 10, she is shocked to discover it is worse than she remembers.
