Peculiar Puglia

Holy shit, they are drystacked!
Plus clever...

Beautifully worked
water-channelling stones on this sill direct rainwater to a
single drip point, which in turn directs it to an underground
cistern via an accessible sink. After looking at dozens of
these amazing buildings, I'm sure that this collected water
is routed down through the building's drystack walls!
The routing was probably made leakproof with plaster, as
plaster was also applied to the inside of the dome upon
completion of the stone laying. The cistern sits below the
trullo, where evaporation is minimized and convenient
access is had. This integrated water catchment helped
insure survival in an arid land.

They are amazing, maybe BigV will rethink his roofing method.

Thanks cf (and the lovely Mrs cf) for sharing your trip.
