Alberobello, distant about 22 miles from Conversano, is UNESCO
World Heritage Site for the unique architectonic historic centre made
of Trulli. The Trulli are dry stone huts with peculiar conical roofs.
Some elements of these buildings probably date back to 1500BC, but
the oldest preserved Trulli we know today have been erected in the
14 th century, under the reign of Robert of Anjou, prince of Taranto
and then King of Naples. The dry stone construction, with no use of
mortar, was imposed to the new colony (Alberobello) because it
allowed an easy demolition to avoid the taxation imposed by the
Reign of Naples.
