The Benedictine nunnery on the lower slope of the Festungsberg is reached by a steep stone staircase from Kaigasse. The late-Gothic abbey church is small but extraordinary: a sensitive 15th-century rebuild that kept Romanesque elements, with original wing-altar paintings still in place.
The nuns are an enclosed order, so most of the convent is off-limits, but the church and cemetery are open and almost always empty. Get here in the late afternoon when the light slants through the choir windows.
