Mount Namsan (265m) is first and foremost a historic site, as the bonghwadae (monticule from which messages were transmitted) at its summit bears witness. This hilltop was vital to the capital's defence during the Joseon Dynasty (1392-1910). Admire the breath-taking panorama over the city from the top. For an even higher view, go to the top of N Seoul Tower (236.7 m). Accessible by cable car.
