No I haven't been there, but thanks for telling me...I always look forward to seeing new castles...
There are two castles very close to my hometown, one is Burg Altena, wonderfully situated on top of a hill and you can overlook the whole city of Altena...the way up to the castle is so small and you can only walk up the hill...the other castle is Hohenlimburg, which isn't very popular in our area...everytime I'll go there, there are usually only few visitors and that's fun, because you can watch the whole exhibition on your own...
