The Trulli of Alberobello are an architectural example of universal value, unique witness, of a now disappeared farming population.
Alberobello was founded between the ‘400 and the ‘500 by some farmers sent by the Counts of Conversano to colonize what was then a forest of oaks. The law then in force submitted any new urban settlement to a royal permission, subject to payment of taxes. To avoid the high taxes, the Counts of Conversano forced peasants to build up only insecure houses, made up of dry stone for easy dismantling in case of a sudden inspection.
This story of precariousness has been transformed into a story of civilization: the civilization of dry stone.
