Letná Park (Letenské Sady) is a large urban park built on Letná Hill, offering commanding views of Prague’s Old Town, including the Vltava River. It’s a popular place for skateboarders, rollerbladers, and cyclists, although the park is large enough that visitors can also relax with a picnic on its grassy areas or tree-lined avenue in peace.Those looking for refreshment can stop for a drink in the popular beer garden here, which is always teeming with visitors during the summer months. For coffee and cake, or perhaps an evening meal, head to the Hanavský Pavilion; this cast-iron, pseudo-Baroque building was constructed at the end of the 19th century and provides some of the best views of the city from its terraces.The giant arm of the Prague Metronome has been swinging back and forth in Letná Park since its construction in 1991. This unique monument sits on the site where a large statue of Joseph Stalin was erected in 1955. The statue was destroyed in 1962, and now the Metronome takes its place upon a marble plinth that was used as the base for the original monument.
