Museum of Tower Clocks

The Tower Clock Museum (Muzeum Zegarów Wieżowych) in Gdańsk is the only museum in Poland devoted to the large clock mechanisms that once measured time from church and town hall towers. It is housed in the tower of St. Catherine's Church in the Old Town and operates as a branch of the Museum of Gdańsk, today within the Gdańsk Science Museum.

What is this museum, and where is it?

The exhibition fills the interior of a tall brick tower beside one of Gdańsk's oldest churches. The museum opened here in 1996. That gives the visit a double appeal: you explore a technical collection and climb into a historic tower that has long shaped the city skyline. St. Catherine's stands in the Old Town, close to the Great Mill, so it fits easily into a walk through the centre.

What can you see?

The core of the collection is tower clocks: large, heavy mechanisms made mostly of iron and bronze. The oldest date to the 14th or 15th century, the youngest were built after World War II. Together they show how the technology evolved, from simple forged frameworks driven by weights to more precise pendulum machines. One especially valuable piece is a cradle clock, one of only a few preserved in Europe.

The museum links history with science. In 2011 it installed a clock based on pulsar signals, the regular pulses of rapidly spinning neutron stars, described as the first of its kind in the world. It shows that the museum looks beyond the past and into how we think about measuring time today.

Is there a carillon in the tower?

Yes. The tower of St. Catherine's holds a carillon, an instrument made of bells played from a keyboard. The current set was rebuilt between 1989 and 1998 and is the largest concert carillon in Poland and Central Europe. If you catch a concert, or just the sound of bells drifting over the Old Town, it makes a memorable addition to your visit.

What happened in the 2006 fire?

In 2006 a fire damaged the church roofs and part of the tower. The museum's exhibits suffered only slightly. After several years of renovation, the church and the museum were reopened to visitors, so today you see the tower restored after those events.

Who is it for?

• Technology and craft enthusiasts who want to see mechanisms up close.
• Families with children, since gears, weights and the story of time are naturally engaging.
• Visitors to Gdańsk looking for a stop less obvious than the most popular sights.
