This is Davor Dolenčić's
cob oven in Croatia. It's a double chamber cob oven with a
chimney stack in the style of a dragon's head (below).
Cob ovens are
stacked with wood and fired to heat the oven chamber. The ashes
are removed to bake food like pizza at around 900F (480C). As the oven
cools other things like bread are cooked, then roasts, beans and
before all the heat has gone you can make yoghurt and then finally,
cook a willing cat. This one, who likes to sit in the warm oven, is called Muri.
