Clock Tower in Vyborg, Medieval clock tower near Old Cathedral in Vyborg, Russia.

The Clock Tower in Vyborg stands on Krepostnaya Street with four clock faces visible from each side of the structure. The building houses a working clock mechanism and rises prominently above the surrounding historic buildings.

The lower tier of the tower was built no later than the first half of the 16th century as the bell tower of Vyborg's Old Cathedral, which was destroyed in the Soviet-Finnish war. After the 1678 fire, a brick octagon was raised on the old stone base between 1678 and 1681. Following the 1793 fire, Johann Brockmann added a third, neoclassical tier with a viewing platform for the fire brigade.

The tower's silhouette appears in paintings by Finnish artists of the early 20th century, often as a symbol of Vyborg alongside the castle. In the mid-19th century, the view of the tower from Vodnaya Zastava Street earned that street the title "the most beautiful street in Finland." The tower also appears in a scene from the Soviet film "The Land of Sannikov," where the adventurer Krestovsky climbs it blindfolded.

The tower is easy to locate since it is visible from many points in the old district and stands near other historic buildings. The surrounding area is easily walkable and provides space to view the structure from different angles.

The clock mechanism was last replaced in 1848 and still runs today. Inside, a wooden shaft between the stair flights carries the heavy weights that drive it. The tower also keeps a alarm bell given by Catherine II, whose ring has sounded for over two centuries.
