The Haut Koenigsbourg Castle is not only in the area, but it's the best-located in a strategic point at 800 meters high. All roads through the Alsace Lorraine pass by it, so the views are fabulous. Although the castle was originally built in the 12th century, fires and other unfortunate events forced its rebuilding. The last time it was rebuilt was in the 19th century and gave it its current appearance. You definitely won't be disappointed if you go see it.
