Local legend of the mountain

The name translates roughly to "upturning of (a) boat" or "upturned boat" in Sundanese, referring to the local legend of its creation. The story tells of "Dayang Sumbi", a beauty who lived in West Java. She cast away her son "Sangkuriang" for disobedience, and in her sadness was granted the power of eternal youth by the gods. After many years in exile, Sangkuriang decided to return to his home, long after the two had forgotten and failed to recognize each other. Sangkuriang fell in love with Dayang Sumbi and planned to marry her, only for Dayang Sumbi to recognize his birthmark just as he was about to go hunting. In order to prevent the marriage from taking place, Dayang Sumbi asked Sangkuriang to build a dam on the river Citarum and to build a large boat to cross the river, both before the sunrise. Sangkuriang meditated and summoned mythical ogre-like creatures -buta hejo or green giant(s)- to do his bidding. Dayang Sumbi saw that the tasks were almost completed and called on her workers to spread red silk cloths east of the city, to give the impression of impending sunrise. Sangkuriang was fooled, and upon believing that he had failed, kicked the dam and the unfinished boat, resulting in severe flooding and the creation of Tangkuban Perahu from the hull of the boat.
