The leather production in Bosa has a long history and dates back to the time of the Ancient Romans. However, the real boom of the industry was registered in the second half of the 19th and in the first half of the 20th century. At that time the city of Bosa was considered the capital of the Italian tanning and saw the fast growth of companies dedicated to this activity. The testimonies of this important period of the Bosa’s leather production are the old tanneries, called in Sardinian Sas Conzas, located along the left bank of the river Temo. The structures were erected outside the city center in order to ensure the adequate water supply and to avoid unpleasant odours related to leather processing in the vicinity of the settlements. A typical tannery of Bosa, built in lime, stone and mud, decorated with red trachyte plaster, was composed of two floors: the ground floor, dedicated to first and main treatments of the leather, and the upper floor intended for finishing work.
The last tannery in Bosa was closed in 1962. In 1989, the complex was declared the National Monument by the Italian Minister for Cultural and Natural Heritage. While visiting the area of the old tanneries do not miss the tannery museum (il Museo delle Conce) where you will discover more about the history and technique of leather processing in the city.
