A few interesting sights around the Dunabe river

 The shores of the river from above.
 Castle "The Stone"; important defense post from the past.
 A tall structure, once used to transport electricity towards Romania. Now abandoned. Also, in the lower-right corner - "The Stone" castle; an old, abandoned building, once been the best restaurant around; and below it - a rocket launching pad with an underground bunker; also abandoned. 
Again, "The Stone" castle
