Alberobello is a small town and comune in the province of Bari, in Puglia, Italy. It has about 11,000 inhabitants and is famous for its unique trulli constructions. The Trulli of Alberobello are part of the UNESCO World Heritage sites list since 1996.
There are many theories behind the origin of the design. One of the more popular theories is that due to high taxation on property the people of Puglia created dry wall constructions so that they could be dismantled when inspectors were in the area.
