Truli are cute stone houses common only in Puglia: the heal of the boot. These houses are made with no mortar, so the shepherds that traditionally lived in them could dismantle and move them to a new location.
The walls are very thick; this makes them warm in the winter and cool in the summer. Normally these houses are alone in the countryside, but there is a very special town called Alberobello where dozens were built side by side.
