I would have something to say about the way this oven has been restored. Note that the upper part is just superimposed without maintaining the proper curvature.
The construction of wood ovens requires skills and craftmanship: they have to withstand the thermal expansion due to temperature higher than usual. For instance a good pizza should be baked inside a wood oven (and using olive tree wood, but that's just a detail) so that the temperature can reach 450 Celsius (note that the oven should be left open during the process). Bread requires lower temperatures (350 Celsius) and the closure of the oven itself.
