The trulli of Alberobello have been designated as a UNESCO World Heritage Site since 1996, thanks to the unique architectural and historical value of trulli houses.
They are considered one of the best examples of vernacular architecture in Europe.
Alberobello is the only inhabited center with an entire district of trulli, and is considered to be the cultural capital of the trulli of the Itria Valley.
It is one of the most beautiful small towns of Italy.
