The Minangkabau Highlands is a mountainous area in West Sumatra, around the three mountains (Mount Marapi, Mount Singgalang, and Mount Sago) in central Sumatra, Indonesia. It is home to the Minangkabau people who refer it as Alam Minangkabau, or the world of Minangkabau. This area formed a kingdom known from at least the 7th century as Malayu.
