The Bosingak Belfry was used during the Joseon Dynasty to keep the time. There were four gates in Seoul that allowed people in and out. At 4 a.m., the bell would ring 33 times and then the gates were opened. At 10 p.m. the bell would ring 28 times and the gates would close. The bell served as a siren. The original bell melted in that spot due to a fire accident. In 1468, the bell was remade and still exists today. However, for preservation purposes that bell now sits in the national museum. The bell that replaced it in Jongno was made in 1985 with contributions from the public. The Bosingak Belfry was built by the Seoul Municipal Government in 1979 and is restricted on normal days. Currently, a daily bell-ringing ceremony is conducted at Bosingak. A special ceremony is held on new Year's Eve where the bell is rung 33 times in front of large crowds.  More Info.Bosingak Bell-Ringing Ceremony- Period: All year round (not available on Mondays)- Time: 11:30-12:20 (Bell-ringing from 11:40/ once a day) Bosingak Bell-Ringing Experience- Application: Online Reservation (Korean)- Foreign visitors may participate in the program on Tuesdays (onsite registration).
