As an island nation with thousands of years of civilisation, Indonesia holds countless mysterious relics of the Archipelago. From Sabang to Merauke, every region has its own tales—be it unresolved legends of the Archipelago, unexplained phenomena in Indonesia, or mysterious cases in Indonesia in modern times.
