Seoul Tower opened to the public on October 15, 1980 and has since become a major tourist attraction. The 236.7 meter tower sits atop Namsan Mountain (243m). The observatory offers panoramic views of Seoul and the surrounding areas.Thirty years and countless visitors later, the structure was renamed ‘N Seoul Tower.’ The letter ‘N’ stands for the tower’s ‘new’ look, which resulted from a 15 billion won remodeling project in December 2005. With a new lighting system and changes to the tower’s overall color scheme, event coordinators can now decorate the tower for the season or events.
