The name Sanji derives from is the designation is recorded as ‘sanjichon’ literally translated the mountainous village (山 地 村).
Under the reign of King Sukjong, the 19th king of the Joseon Dynasty, Jeju province governor at that time, Lee Hyeong-sang dispatched a painter Kim Nam-gil to write tamna Sullyeokdo (a book of paintings depicting various events held in 1702).
Known initially as sanjeo, meaning at the foot of the mountain, the name
was later changed to its current name as the upstream of sanji stream that originates from Hallasan Mountain empties itself into the sea.
Sitting on half-way up the sarabong peak, one of the signature parks in Jeju-do
island, the sanji light house overlooks the port of Jeju.
