    Jane Austen, a famous English writer, was born in Steventon, Hampshire, on December 16, 1775,

and died on July 18,1817. She began writing early in life, although the prejudices(偏见)of her times

forced her to have her books published anonymously.(匿名).

      But Jane Austen is perhaps the best known and best loved of Bath's many famous local people and

visitors. She paid two long visits during the last five years of the eighteenth century and from 1801 to

1806, Bath was her home. Her deep knowledge of the city is fully seen in two of her novels, Northanger

Addey and Persuasion, which are largely set in Bath. The city is still very much as Jane Austen knew it,

keeping its streets and public buildings the well-ordered world that she described so well in her novels.

Center in Gay Street. Here, in a Georgian town house in the heart of the city, you can find out more
