Burg Bibra
Wood Cut engraving of the burg

Model of Bibra in Kloster Veßra by E Heß
Bibra in 1580
I don't know the information that was
used to create the model on the left.  
The only obvious shortcoming is the
height of the keep (tower across from
bridge).  The thickness of the existing
wall implies a taller structure.
