Sas Conzas is a quaint neighbourhood of Bosa, with industrial buildings overlooking the left bank of the Temo originally used for tanning.
The tanning tradition in the area dates back to ancient times; rediscovered in the seventeenth century, it thrived from the mid-XVIII century onwards. Nowadays, all that is left is mainly buildings dating from the XIX century set out in a row along the riverbank, to make it easier to collect the water needed for tanning.
Work ceased around 1960 and in the 1990s, the group of buildings was restored. The tanneries included those of the F.lli Solinas, Mocci-Marras and the Poddighe family, which currently houses the Museo delle Conce. The museum illustrates the techniques used and displays industrial archaeological artifacts, like the basins used for tanning the leather.
