"Archduchess Maria Anna of Austria (Maria Anna Josepha Antonia; 6 October 1738 – 19 November 1789) 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 Frauenstift 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." - (en.wikipedia.org 29.04.2021)
