Castle Frankenstein

After we left Heidelberg we headed home on the Autobahn. There is no
speedlimit so we hit about 110mph. Halfway back we saw a sign for Berg
Frankenstein. We decided to check it out. It's at the top of a long
dark winding road and the place is in ruins. There was no one there
and it was dark, old and mysterious. The weather was cold and windy
like Autumn has arrived in force. Rusted door locks, secret
underground rooms and forest all around. It gave a 360 view of the
city. You can see the Frankfurt skyline in the background.
