Jongno ("Bell Street") is one of the oldest major east–west thoroughfares in central Seoul, South Korea, connecting Sejongno to Dongdaemun. It remains one of Seoul's most important financial and cultural areas to this day. Many important landmarks are located along its length, including the Bigak pavilion at Sejongno, the Bosingak belfry (hence the street's name), Tapgol Park (Pagoda Park), the Jongmyo royal ancestral shrine, and the aforementioned Dongdaemun (Great East Gate). Seoul Subway Line 1 passes under Jongno. The western end of Jongno is serviced by Gwanghwamun Station (Seoul Subway Line 5), and Jongno 3-ga Station is serviced by Subway Lines 1, 3, and 5. Because of a large number of shops, stores and groceries along the area, the word "Jongno" is often used in the Korean language to express "Town Square."
Jongno Tower is a 33-story office building. Its top floor is equipped with a restaurant and bar which is famous for its view of Jongno and other areas of Seoul. The tower is located near Jonggak Station of Seoul Subway Line 1.
Insadong-gil, a street famous for its traditional attractions, including galleries, souvenir shops, and restaurants, is accessible directly from Jongno (Jongno 3-ga).
