Located in Letná Park, this giant metronome was designed by Vratislav Novak and installed in 1991. It was erected on a spot that was once occupied by a monument to Joseph Stalin. This is the reason why the surrounding area is often referred to as "Stalin". This functional metronome now serves as a popular meeting place, offering splendid views of the city.
