Here, like elsewhere, the mill and bakery are connected because the place of flour production and processing are part of the same production process. The wheat is ground with large lava millstones, five fine examples of which are seen in the bakery. These are formed by two elements: a lower cone-shaped part (meta) and an upper hourglass-shaped part (catillus). The grain is poured into the catillus that turns when pulled by slaves or animals and grinding the grain and then dropping it below.

Bread was baked in different shapes in the large oven at the centre of the building and was regularly sold in the same place in a small room with a counter. The counter is missing in this bakery; the bread was probably produced either on commission or sold wholesale or by street vendors, called libani.

Date of excavation: 20s of the 19th century.
