The Verzasca valley is on the south side of the Swiss alps in canton Tessin, Italian is the official language there. Granit is the traditional building materiel, also for baking ovens, we came across a couple on a recent family hike.
Communal oven village of Solongno: I had a look inside, the brick arch was low enough to make it a decent bread oven, it sloped down to the floor at the back, sort of pizza oven style. This oven was built long before pizza was invented though. There would have been sufficient room inside for three adults to lay sleeping bags out and rest for the night....a creepy thought. I estimate that 70 round 500g. loaves would fit in. It was to dark inside to see, but i believe the oven has a single exhaust port up front, directly behind the oven door, that exits under the roof.
Stone is bolted onto the inside of the oven door to work as a heat battery.
The village of Solongno, canton Tessin Switzerland.
The hiking trail a few kilometers south of Sologno passed through this abandoned "stone age" settlement. The oven door was padlocked, it looks though to be built in the same stlye as the Solongno oven, again with no chimney poking out of the roof. The bake oven is located right of centre in the photo below.
