The tower's LED lighting turns blue when the concentration of fine dust in Seoul's air is below 45μg/m³.
It was designed as a radio and television transmission tower before opening to the public in 1980.
The tower's height is measured from the base of the mountain, meaning its actual height above sea level is 479.7 meters.
The rotating restaurant completes a full 360-degree revolution every 48 minutes.
The 'Locks of Love' tradition began organically when visitors started attaching locks to the railings to represent eternal bonds.
The tower was officially renamed 'N Seoul Tower' in 2005 following an extensive renovation, with 'N' standing for Namsan, New, and Nature.
N Seoul Tower, also known as Namsan Tower, stands atop Namsan Mountain in central Seoul, serving as both a communication transmission center and a panoramic observation point. Originally built in 1969 as Korea's first integrated transmission tower, it reaches a total height of 236.7 meters. The structure features a multi-level observation deck offering 360-degree views of the Seoul Metropolitan Area. The base and tower contain retail spaces, a rotating fine-dining restaurant, and a casual café. The exterior is equipped with LED light installations that change color based on air quality levels in the city. Surrounding the tower is a public plaza featuring thousands of padlocks placed by visitors to symbolize enduring relationships. Access to the peak is provided primarily via a cable car system or a pedestrian walking path. It remains one of the most recognizable landmarks in the South Korean capital.

Check the air quality index before ascending to ensure clear visibility for your skyline photos.
Visit the lower terrace levels for free views of the city if you prefer to bypass the paid observation deck.
Bring a marker pen if you intend to participate in the 'Locks of Love' tradition, as they are not provided on-site.
Avoid visiting on heavily polluted or foggy days, as the observation deck's primary appeal is the clear city view.
