Erfenstein / Spangenberg
Below, a view along the castle looking towards Efrenstein.
The photo at left and below are very unique.  Why?  Because this area was PRIVATE, even though there was no sign indicating such.  My wife and I entered through an unlocked gate and began to further explore.  As we went up the stairs we were greeted by an older gentleman who began chewing us out.  I apologized not realizing I was intruding, but at the same time it would have helped if he labeled the entrance properly. 

The stairway below goes down to an entranceway that is now gated off and to what appears to be some type of residential quarters with a window facing into the valley.
Right, the main entrance into Spangenberg.  The tablet to the right is the basic history of the castle.

Below the main structure resting on a sandstone table rock.
Left, the entrance pictured here is PRIVATE.  Do not enter!  But when you go up to it, look above and you can see the breteche above the gate to provide overhead protection.
