Just outside the historic centre, Iglesias' main museum is dedicated to the town's mining heritage. It displays up to 70 extraction machines, alongside tools and a series of thought-provoking black-and-white photos. But to get a real taste of the claustrophobic conditions in which the miners worked, duck down into the recreated tunnels. These were dug by mining students and were used to train senior workers until WWII when they were used as air-raid shelters.

Also on show is a collection of 8000 carefully labelled rock and mineral specimens sourced from Sardinia and around the world.
