I spent two years (1958-59) in Frankfurt and we often took a drive up the Taunus mountains on a road that took us through a small town that had the ruins of a castle (or some such building) then on through the beautiful forest and then back down the mountain not far from Frankfurt. Does that sound familiar to anyone? If so what was the village. I have looked at Konigstein but it quite a bit larger than I remember the village being, but that could easily be so after all these years. We are planning a trip to Frankfurt next spring and I would like to make that drive again.
