The trullo is usually circular and the interior spaces are distributed around the central compartment. The thickness of the walls and the few windows ensure an optimal thermal balance, warmth in winter and cool in summer.

What were Trulli used for?

Their style of construction is specific to the Itria Valley in the region of Puglia. Trulli were generally constructed as temporary field shelters and storehouses or as permanent dwellings by small-scale landowners or agricultural labourers.

Why do the trulli have symbols painted on their cones?

Many cones have symbols painted on them. The symbols are painted with lime. Legend has it that they were painted for magical or propitiatory rites. The meaning of some common symbols are to protect the family living in the trullo from the evil eye, the worship of some deity, and the hope for a good harvest.
