The sleeping bear cub is my favorite. It looks like he has a string by his bed to turn on the light like I do. The wolf head is cool, a bit lopsided, but maybe influenced by Picaso.
I'm not sure that any of these were man made, although I can see how the brick shaped rock and the walkway would appear so. However, having noted that your in Albania, I think that these are just ophiolites, chunks of long ago ocean floor that has been pushed up to the surface.
I sure would like to metal detect there though, with it's long history!
