Via del Ferro is an easy trail that you can enjoy on your own at the end of your visit to the Etruscan necropoleis or while waiting for your guided visit to start.
The trail, of great environmental and natural interest, winds its way around impressive mound tombs and antique structures where iron was worked and which form part of the industrial district of Populonia.
These areas are enclosed by walls, within which some of the main activities linked to the production of iron were carried out: the presence of thick layers of a dark red, almost purple, colour inside these areas indicates that hematite was roasted here; roasting was necessary to prepare the mineral before being transferred into the furnaces.
