Long Ya Men (simplified Chinese: 龙牙门; traditional Chinese: 龍牙門; pinyin: lóngyámén; Malay: Batu Berlayar) or Dragon's Teeth Gate, is the name Chinese explorer Wang Dayuan recorded for Batu Belayar, a craggy granite outcrop that formerly stood at the gateway to Keppel Harbour in Singapore. In his description, “The strait runs between the two hills of the Danmaxi (Temasek) natives which looked like dragon’s teeth.” From there, the name Long Ya Men or Dragon Teeth’s Gate was born.
