In May of 2015 I traveled to the Republic of Korea. One of the places I visited was N Seoul Tower ( N서울타워) where you can get amazing views of the city.
The tower measures 236.7 m (777 ft) in height from the base and tops out at 479.7 m (1,574 ft) above sea level. It changed its name to N Seoul Tower in 2005. The "N" stands for 'new,' 'Namsan,' and 'nature.'
The following video is what the elevator ride is like going both up and down. Video was recorded with my Canon Vixia Hf M41.
