i trulli patrimonio UNESCO
Alberobello is not an ancient town,
although its origin is cloaked in folk myth. It appears it
has its origins in the 15th century, and by the 16th had a
mill and tavern built by one of the Counts of Conversano,
Gian Girolamo II, in the hope of attracting farmers to create
another patch of feudal Italy that was in his control rather
than the distant Naples lords..
history says that the trulli were created at this time, so
that the Napolitan taxes on permanent settlements and buildings
could be avoided. Building without mortar enabled the houses
to be dismantled as soon as the locals got wind of a tax inspector
coming their way - and rebuilt once the tax collectors had
completed their inspections.
is an improbable distortion, but persists in popular mythology.
It is likely that the origin of trulli is much older. The
Murge, or Mugia, high plains of the central Puglia, were not
ideal for agriculture, being of thin red soil on top of limestone.
Until a few hundred years ago the area was mostly covered
with oak forest - indeed Alberobello draws its name from the
"Sylva Arboris Belli", the extensive woodland which
covered the area before being worked for farming purposes.
today it is difficult to plough or rotavate a field without
having to spend much time dealing with the quantity of stone
upturned. Historically this provided most of the material
for constructing the extensive dry-stone walling which characterises
the region. And the trulli.
practical advantage of a trullo (trulli is the plural) construction
is that thick limestone walls give protection from the cold
of winter. Conversely, in summer the temperature inside a
trullo is a welcome several degrees less than the outside.
So you have a combination of a widely available building material
with a practical advantage.
why did trulli evolve as they did, with a construction unique
in the world?
the myth nor the commonsense approach answers this question
