The Nonne is a roughly 18-metre-high, isolated, standing sandstone rock and climbing peak in Saxon Switzerland in Germany. The rock is located southeast of Rathen, east of the rock chain of Rauenstein.
In the Middle Ages the rock was used in the 15th century as a watchtower, similar to that on the other side of the Elbe, Neurathen Castle. To that end the rock crevice below the summit plateau was widened into an artificial cave, used as a guardhouse. On the eastern side there are more traces of hammers. In addition, an artificial, earth embankment, about 35 m long, was built. Archaeological investigations ins 1963 brought to light pieces of ceramic, the spindle whorl of a spindle, the site of a hearth and fragments of charcoal.
