These white marble excavation sites are located within the imposing and ecologically rich Apuan Alps. Since Roman times, the white stone of Carrara has been considered the finest marble. Ancient excavation techniques preserved these mountains for centuries, but the acceleration of new extraction technology has increased the destruction. Here in the last 30 years, more marble has been removed than during the past two millennia.」4月8日 11時08分
