Metronome

The Prague Metronome (Pražský metronom) is a 23-metre kinetic sculpture standing on a massive concrete plinth in Letná Park, overlooking the Vltava River and the historic centre. The plinth itself carries as much historical weight as the artwork: it is the same platform that once held the world's largest monument to Joseph Stalin — a 15-metre-tall group sculpture unveiled in 1955 and demolished just seven years later after Khrushchev's de-Stalinisation. The metronome was installed in 1991, designed by Vratislav Novák and officially titled Time Machine, with a plaque reading "In time, all things pass." Today the site is a popular gathering point for skaters and locals, and the terrace offers one of the widest panoramic views of Prague — taking in the Charles Bridge, Old Town, and the entire Vltava bend — with easier access and fewer tourists than most official viewpoints in the city.
