Nonnberg Abbey is located on Nonnberggasse, along the eastern side of Festungsberg hill, in Salzburg, Austria. The abbey was constructed on the site of the old Roman city of Juvavum, under the guidance of Saint Rupert of Salzburg, sometime between 712 and 715 A.D. Saint Erentrude of Salzburg, probably a sister or niece of Rupert, was the first abbess of Nonnberg. The original building was razed by fire in 1006, then again in 1423, eventually rebuilt between 1464 and 1509, and enlarged in 1624. The current Baroque style is reflective of work done in the 1880s. In 1924 Maria Augusta Kutschera entered the Benedictine Monastery here as a postulant with the intent of becoming a nun. Instead, she would marry Georg von Trapp in 1927 and become famous as Maria von Trapp. Her story would be told in the Broadway production The Sound of Music in 1959. The movie version was filmed on location on Salzburg in 1965 and several scenes were shot around the abbey grounds. Nonnberg remains the oldest existing nunnery in the German speaking world. It is now part of the Historic City Centre of Salzburg, a UNESCO World Heritage Site.
