The mining site is located near Masua (Iglesias) along the south-western coast of Sardinia. Porto Flavia which takes its name from its designer’s first daughter, was built in 1924 by digging up a mountain for about 600 metres. In the lower of two galleries placed one on the top of the other, a conveyor belt received the ore from the underground deposits and by means of an ingenious mobile arm transferred it directly into the holds of cargo ships at anchor. This clever solution managed to revolutionise the system of loading ores. Till then it had been transported in baskets on the shoulders of  “galanze” from Carloforte and carried on 20-30 ton sailing boats. Now it is possible to visit the entre tunnel. Visotors can admire this fascinating scenery and also this example of engineering and construction technique.
