Archduchess Maria Anna of Austria (died 1789)

Archduchess Maria Anna of Austria was the second child of Francis I, Holy Roman Emperor, and Maria Theresa, Queen of Hungary and Bohemia. As a child, and for a time the eldest surviving child, she was heiress presumptive, but she suffered from ill health and physical disability, and did not marry. In 1766 she became abbess of the Theresian Institution of Noble Ladies in Prague. Soon thereafter she moved to Klagenfurt and remained there for the rest of her life. Her palace in Klagenfurt, the Mariannengasse, now houses the Episcopal Palace.
