The zelkova trees that grow in Korea belong to the species Zelkova serrata, which are commonly found across Korea, Japan, China and Taiwan. The flowers bloom in May and bear ovate drupes that ripen in October. Since ancient times, zelkova trees have been favored for their shade, and in most Korean villages are called jeongja namu (“pavilion tree”).The big old zelkova tree in front of Segan Village is named Hyeongosu, meaning “Drum-hanging Tree” and is assumed to be some 520 years old. It stands 15 meters tall and has a girth of 7 meters at chest level. The tree’s name comes from a local legend that says General Gwak Jae-u recruited a righteous army by beating a drum hung from this tree when Japan invaded the country in 1592. As this was the first instance of a righteous army being mobilized during the seven-year-long period of Japanese invasions, annual memorial events for righteous army activities during the war begin with the lighting of a flame here.
