The N Tower has four floors: 1F, 2F, 3F, and 5F (most buildings in Korea avoid having fourth floors). 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. The tower offers a digital observatory with a 360° panoramic view that showcases Korea's history through 32 LCD screens. This is located on the third floor of the N Tower.
