The first level's outer battlement as you work up the keep. It's hard to say whether or not these walls had been crenelated, as they have had some considerable reconstruction. However, they probably were not as most reconstruction work is done with the intent of following the original construction.
Right and below, two views of the reconstructed stairways and platforms within the keep. As can be seen, this was more of a fighting area than one for living, so watch tower may be a more appropriate term to use.
A view looking down on the outer stairs, giving some idea how the entrance might be defended. However, it would appear that these stairs and the outer entrance may have actually been enclosed in the portion of the castle that encompasses the stairs.
Right, I'm standing on the second level's battlement.
Looking down at the restored Wursthaus.
A look down at the first level and how the shape differs from that of the entire keep.
The photo at lower left is from the same angle as the one above looking down on the outer stairs... only one level higher.
Below, moving up into the last portion of the keep demonstrates why it is more appropriate to call it a watch tower! The stairs were narrow and steep and you literally go up them hand-over-hand.
But the view from the tower is spectacular and well worth the climb.
