Ganghwa Sagiri Trifoliate Orange Tree

The trifoliate orange tree is mainly distributed in the Yeongnam and Honam regions of Korea, and also grows in Japan and China. It is speculated that the trees in Korea and Japan were introduced from China. The fruit and peel are used as medicinal ingredients, and the thorns on the stems make it suitable for use as orchard fences. The Ganghwa Sagiri trifoliate orange tree is estimated to be about 400 years old, with a height of 4.7m and a root collar circumference of 2.2m. Ganghwado Island is where King Gojong of Goryeo (reigned 1213–1259) took refuge from Mongol invasions, and King Injo of Joseon (reigned 1623–1649) also sought refuge there during the Jeongmyo Horan (Manchu invasion of 1627). It is said that during these times, as a means to block foreign invaders, walls were built on Ganghwado Island and trifoliate orange trees were planted outside the walls to prevent easy access by enemies. This trifoliate orange tree is presumed to be a survivor from those plantings. The Ganghwa Sagiri trifoliate orange tree holds historical significance as a relic of national defense planted by our ancestors to prepare for foreign invasions, and it is located on Ganghwado Island, the northernmost limit where trifoliate orange trees can grow. It is designated and protected as a Natural Monument.
