Tower Clock Museum

The Clock Tower Museum in the tower of St. Catherine's Church in Gdańsk houses a fascinating collection of historic timepieces spanning five centuries. As part of the city's Historical Museum, it focuses mainly on mechanical clockworks from the seventeenth and eighteenth centuries, which are restored and preserved here. One particular highlight is the pendulum clock installed in 2016, which, at more than thirty meters, has the longest pendulum in the world. Visitors can also experience the church's carillon, which consists of fifty bells and is played on a mechanical keyboard. A modern pulsar clock that receives extremely precise signals from space can also be seen in the church interior.
