The white tower like structures on some of the roofs are water containers: a truck arrives every couple of days with a delivery.
In the past, water was obtained the hard way! either a dug well or mountain run-off, a small wall would be constructed near a fissure in the rock and the water trapped for later use.
With the construction of roads (rather than Donkey tracks) along with electricity: life has become a lot less arduous.

Very interesting! What a beautiful setting in the first photo. Those rugged hills must have a million stories to tell.
Yes it is isn’t it…… the hills go back at least 600 million and human habitation probably bronze age.
