Millstone quarries are the sites where hard and abrasive stones were
extracted to be fashioned into the querns or millstones to grind flour
for bread, the staple food of our ancestors. These stones equipped the
different grinding mechanisms, from the Prehistoric hand-driven saddle
quern to the sophisticated industrial mills driven by wind and water.
These little known extraction sites, ubiquitous throughout the European
landscape, have been largely neglected. This study, focusing on the
southern half of the Iberian Peninsula, attempts to draw attention to
these often spectacular sites that merge so well with nature.
