Sawahlunto is one of the mining towns in West Sumatra. It was first established as a town in 1882 by the Dutch along with coal mining operations. Coal was discovered in the mid-19th century by Ir. de Greve. It was then suggested to the Dutch that coal should be mined in the area because coal was needed for industry and transportation. After the discovery of coal the area was frequently visited by geologists. Coal mining was pioneered in the area after the eventual "surrender" of the area to the Dutch in 1876. After the golden period of mining and the closure of the mine sites, Sawahlunto became a ghost town and the population declined. In 2004, the city's policy became to turn Sawahlunto into a tourist city, since when the population has increased. In 2014, 29 percent of its income came from tourism, while only 23 percent came from farming .
