Most drawings are already gone, not really worth stopping
I'm glad people can't get to the drawings anymore
You have to go see them
Historic site, well preserved. Free of charge. Not very big, but worth a stop if you drive by anyway.
Most interesting parts have been removed. Not much to see. Would be nice with more information boards on the background. Nice short walk though.
Nothing special to be honest but worth for a quick stop on the way.
Not much left to see. Have to use your imagination
If you happen to be passing it's worth a look, but there's not that much to see.
