Finally today I found a hidden place that I want to know. Isn’t very old place, just from 1948. In the forest is possible to find 3 mines of water, they are close because they are using when is enough water.
The west of Centelles the mountain is like a wall, there is a waterfall but should rain a lot too see. The river is subterranean, but isn’t to important, necessary to have local water, because is the basic element to live.
I like find places like this, the history of people that try to get water to be a better village. Time and the forest make that people forget this place.
