Sawahlunto is a city in West Sumatra, 90 kilometers from Padang. This city covers an area of about 5.86 km² and is populated by 15,279 people. It is the only coal mining spot in West Sumatra and was once known as the Black Pearl. It was first established as a town in 1882 by the Dutch, coinciding with the flourishing coal mining operations during that time. However, coal-mining exploitation is no longer the prime money earner for Sawahlunto. In recent years, this city is more well-known for its beauty as a heritage city. There are numerous historical buildings adorned with Dutch quaint colonial artworks and architecture around this city, which are still functioning for contemporary purposes. Today, Sawahlunto is a unique tourist destination that offers nostalgic traces of an old mining town.
