Building means leaving a void somewhere.
The Po Valley, storage of water-piled debris, is constantly dug through to collect materials for building and public works.
In the lands around the Secchia river, below the sight level and behind containment embarkments, quarries open like landscapes of emptiness, the negative of what is shaped elsewhere, where the matter is mined, fragmented and piled-up, waiting to be used to build the living areas. Building means creating a hole somewhere else.
In a few decades time, once-cultivated lands, are dug into, ground, and transferred, and the remains are left uncultivated and eventually reconverted into environment recovery projects. Where water springs from the aquifers, new lake environments, such as the Curiel lakes in Campogalliano (MO) emerge.
