As an island nation with a civilisation spanning thousands of years, Indonesia holds countless mysterious relics of the Archipelago. From Sabang to Merauke, every region has its own stories—whether unresolved legends of the Archipelago, unexplained phenomena in Indonesia, or mysterious cases in Indonesia in the modern era. We will present these not as mere folklore, but with analysis based on the latest research, including archaeological data and documented evidence. This way, we can critically distinguish myths and facts of the Archipelago, while appreciating the complexity of our homeland’s history.
