Bell Tower Clock
The Cathedral Bell Tower clock is the oldest in the city. It is thought to have been mounted there in the 17th century. The mechanism of the bell tower clock is about 350 years old. It only once needed any serious repairs, in 1803. The residents of the city are helped in keeping track of time by the bells which were cast by the well-known craftsmen Jan De La Marche and Gustav Mörk, and which sound every quarter-hour and hour. Two surviving old faces of the clock can be viewed at the top of the Bell Tower.
