Fossen Fussen is the end of Romantic Avenue and the nearest town to Swan Castle. There is a highland castle on the ridge of the town. You can walk into Hernsburg along the winding stone ramp from the town Guangyuan. When you look at the castle, the window sills and walls of the whole castle are painted, full of fantasy, colorful and three-dimensional, like a picture of a children's story book. The Bell Tower and Chapel in Hernsburg are currently open to visitors. What's worth visiting is that the post-Gothic art works, as well as the amazing sculpture and latticed ceiling hall, are among the best preserved medieval castles in Bavaria.
