N Seoul Tower is a communication and observation tower located in Namsan Mountain, central Seoul, South Korea. Built in 1969, at a cost of approximately $2.5 million, and opened to the public in 1980, the tower has been a symbol of Seoul and 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 has also been known as the Namsan Tower or Seoul Tower. After the tower's original owner merged with the CJ Corporation, it was renamed the N Seoul Tower (official name CJ Seoul Tower).
Many visitors ride the Namsan cable car up the mountain, and then walk to the tower. The tower features a gift shop and restaurants on the ground floor. Visitors may go up the tower for a fee. There are four observation decks (the 4th observation deck, which is the revolving restaurant, rotates at a rate of one revolution every 48 minutes), as well as gift shops and two restaurants. Most of the city of Seoul can be seen from the top. Close to N Seoul Tower is a second lattice transmission tower.
