The 236-metre-tall (774 ft) structure marks the second highest point in Seoul and is considered a local landmark.

[3] Currently, the tower broadcasts signals for Korean media outlets, such as KBS, MBC, and SBS.

Built in 1969 at a cost of approximately US$2.5 million, the tower was completed on 3 December 1971, designed by architects at Jangjongryul, though at the time the observatory was not built, and the tower was only used for transmission purposes, primarily to block North Korean television and radio from reaching Seoul.

N Seoul Tower, along with Changdeokgung, was selected as one of the world's top 500 tourist destinations in Lonely Planet's Ultimate Travel List.

The lobby has the entrance to the observatory, an information desk, a museum, a cafe, children's theatre, and a nursing room.

The third floor (3F) of N Seoul Tower has a Korean restaurant called Hancook,[6] and a digital observatory with a 360° panoramic view that showcases Korea's history through 32 LCD screens.

Each year, approximately 8.4 million visit the N Seoul Tower, which is surrounded by many other attractions South Korea offers, including Namsan Park and Namsangol Hanok Village.

[10] Visitors may go up the tower for a fee that differs for the following groups: children, elderly and teenagers, and adults.

During Earth Hour, lights are turned off nationwide to promote energy conservation awareness.

Securing the padlocks on the fences filled with locks of previous participants, the key is often thrown away as a symbol of everlasting love.

The coins are collected and donated to help develop schools in China and Southeast Asia, especially in underdeveloped areas.

The observatory not only offers a 360° view of the city, but also exhibits 600 years of Korean history through 36 LCD screens.

On level 4, there is a 24-metre-long (79 ft) wavy structure decorated with images of wish lanterns, flames and patterns of dancheong to represent beautiful sky across Seoul.
