The nature of Milos reminds us often about the mining history in the area. Especially the Sulphur Mines located on the eastern part of the island above Paliorema beach. The mines were used from 1890 to 1960 with some interruptions in between. If you visit the mines you will be able to imagine how it used to work due to the remains of the buildings, galleries, bridges and rails and almost intact machines like wagons on the tracks and spare parts in store rooms. It needed about 200-300 workers to operate the mines. The workers had very hard work conditions. They used to stay in Paliorema for the whole week and went only home to their families during weekends, crossing the island by foot. The job was very unhealthy due to dust and extremely hot temperatures. Sickeness like lung infections, tuberculosis, blindness and work accidents have been reported. The average annual production is stated as 2000 tons sulphur.
