Larderello is a fraction of Pomarance, in the province of Pisa.

This tiny fraction has only 850 inhabitants, it is situated at 390 meters above sea level on the metalliferous hills and is in part owned by the Enel Electricity company.

The town took its name from the Franco-Livornese industrialist François Jacques de Larderel that in the nineteenth century perfected the technique for the extraction of boric acid, thanks to the use of natural steam that brought the muds of the “lagoni” to evaporate the water contained and thus obtain the acid.

The small area is located in the center of the so-called “Devil’s Valley”, so called because its landscape characterized by columns of white vapors, mentioned even by Dante Alighieri among the chapters of his “hell”.
