During the summer shepherds lived in camps called "katun" in shacks which had stone base, wooden log cabin or double and wattle walls and roofs either constructed from wooden panels or thatch.
This is another "katun" shepherd summer camp from Bosnia. This one is next to the Prokoško Lake under Vranica Mountain. Apparently these and many other katun huts are now rented to hikers...
You can read about this calendar in my post "Two crosses"
Another, now abandoned "katun" shepherd summer hut from Montenegro. Kuči mountains, Montenegro.
In Serbia these shepherds huts are called bačija.
This is one of the bačija shepherd huts from Rudno on mountain Golija in Serbia.
Here is another one from mountain Kopaonik, Serbia
And another one from Pester highlands in Serbia
