Trulli (singular: trullo) are traditional dry-stone huts in Apulia with a conical roof. Their style of building is unique to the Itria Valley in the Murge area of Apulia, Italy. Trulli were usually built by small business owners or farm workers as temporary field shelters and storage sheds or as permanent homes. In the town of Alberobello, which is in the province of Bari, trulli are built into whole neighborhoods. The 19th century, especially the last few decades, was the best time for trulli. This was because wine-making became more popular during this time. Image by Patrick Denker is licensed under CC BY 2.0.
