One of the unique museums of Northern Europe. Established in 1984, the museum is located in a restored 19th-century building. It exhibits originals, models and replicas of ancient calendars, sundials, hourglasses, water, and fire clocks, as well as original 17th–20th-century mechanical clocks. The exhibition at the Clock Museum consists of two parts. The first floor reveals the principles of time measurement and the evolution of clock construction from antiquity to the present day.The second floor showcases the changes in the shape and design of mechanical clocks from the renaissance to modern styles (16th to 20th centuries). The exhibition presents the works of famous European and Lithuanian clockmakers: Theodor Tarasowig of Vilnius, as well as Abraham Louis Breguet and Theodore Perret of Switzerland, among others. Here you will find over 1,700 original and rare clocks, watches and reconstructions. There is also a park of sundials in the courtyard of the museum.
