Ruin "Nollig" near Lorch
Probably not a castle ruin but a habitable watch tower, built in the 14th century as a 3-storied half-timbered building that was surrounded later with thick walls. Until today it is highly controversial if the Nollig belonged to the former fortification of Lorch.
Today it is private property and so can not be visited.
You will pass the Nollig on your hiking tour between Lorch and Kaub.
